Why Apple’s A5 Is So Big, And Siri Is 4S-only

Stephen Shankland at CNET reports on a possible explanation as to why Apple decided to make Siri an iPhone 4S exclusive:

Apple’s A5 processor includes noise-reduction circuitry licensed from a start-up called Audience, and a chip analyst believes that fact resolves an iPhone 4S mystery and explains why the iPhone 4 lacks the Siri voice-control system.

Audience revealed details of its Apple partnership in January, when it filed paperwork for an initial public offering (IPO) of stock. Teardown work from iFixit and Chipworks revealed a dedicated Audience chip in the iPhone 4, but the iPhone 4S integrates Audience’s “EarSmart” technology directly into the A5 processor, the company’s S-1 filing said.

Audience confirmed in its filing that Apple signed an agreement to pay royalties for the intellectual property used in the A5 processor in the “three months ended December 31, 2011″, suggesting that only the iPhone 4S version of the A5 (the A5 CPU is also used on the iPad 2) supports Audience’s technology. Audience also said that Apple is a licensee for the next-generation IP, although they won’t be contractually forced to use it; iPhone 4-era technology from Audience also has advanced noise-reduction, but it was only with the second-generation product (the one on the A5) that Audience perfected recognition/reduction at arm’s length — thus allowing for features like voice control through Siri.

Integration of Audience’s EarSmart on the iPhone 4S’ A5 could explain why Apple decided to not offer Siri on older devices, and why it will likely only feature the voice-based assistant on newer devices going forward. A number of unofficial hacks to enable Siri on older devices surfaced in the past months, albeit with mixed results.

According to developer and hacker Joshua Hill, the latest jailbreak for devices running Apple’s A5 processor has been downloaded more than one million times in one day, Cult of Mac reports. The new jailbreak — dubbed Absinthe — was released for Mac OS X on Friday after months of speculation as to whether it was possible to hack into Apple’s new CPU architecture. The Absinthe jailbreak supports the latest version of iOS, iOS 5.0.1; iOS 5 was released in October, and users of iPhone 4S and iPad 2 have been waiting for a fully untethered jailbreak solution compatible with their devices since then.

According to Cult of Mac, one million downloads were achieved on Mac OS X alone as a Windows version of the jailbreak was released after the initial 24 hours. As Alex Heath notes, this figure is noteworthy as it seems to confirm that interest in jailbreaking devices hasn’t died down after the release of iOS 5; the operating system introduced more than 200 new features for iPhone and iPad as we detailed back in October. If anything, it was iOS 5 itself that led developers to create new apps and tweaks that are taking advantage of the latest features offered by Apple such as Notification Center and Twitter integration.

To put the A5 jailbreak’s numbers into context: one million downloads were reached in 24 hours by JailbreakMe 3.0 as well when it came out for iOS 4 devices last summer. Currently, the Absinthe jailbreak is available for OS X and Windows machines over at Greenpois0n.com.

Update: With a tweet, MuscleNerd says that 205,000 new Cydia accounts were created by Sunday morning, suggesting that a large percentage of Absinthe early adopters were users who had jailbroken their devices in the past, thus likely already having a Cydia account. See update below.

Update #2: Whilst we assumed “new Cydia installs” referred to the amount of new accounts created last weekend, MuscleNerd has clarified the figure indicates how many times Cydia was launched on a unique A5 device.

Update #3: Cydia creator Saurik chimes in with more numbers, clarifying that 205,000 were the iPhone 4S units with Cydia until Sunday morning.

Update #4: And last, the Dev-Team has published a blog post with the official numbers since Friday morning:

  • 491,325 new iPhone 4,1 devices (4S)
  • 308,967 new iPad 2 devices
  • 152,940 previously jailbroken (at 4.x) iPad 2 devices

For a total of 953,232 new A5 jailbreaks in over three days. At this point, if the previous 1 million/24 hours figure is to be believed, it’s possible 1 million downloads actually happened in 24 hours, but many users couldn’t immediately run Absinthe due to the server problems that affected Greenpois0n.com.

According to a new blog post published by jailbreak hacker pod2g, the long awaited jailbreak for A5 devices (iPad 2, iPhone 4S) should be “a matter of days” now. The blog post reveals that developers @planetbeing and @saurik (the creator of Cydia, marketplace for unofficial iOS apps) made their contributions to finding an exploit for the A5 chip, which has been a major issue for hackers trying to figure out a way to hack into Apple’s system in the past months.

pod2g, creator of the iOS 5.0.1 jailbreak for A4 devices, notes that there “should be nothing left” blocking the release of the A5 version. A precise release date, however, hasn’t been provided in the blog post.

For updates, you can head over pod2g’s blog and Twitter account. The A5 jailbreak has seen a “dream team” of hackers like Saurik, Planetbeing, pod2g, MuscleNerd (iPhone Dev Team) and p0sixninja (Chronic Dev Team) working together to find a way to break out of Apple’s sandbox and release a public version of the jailbreak.

In our “Let’s talk iPhone” event rumor roundup, we noted Apple could announce a new Apple TV on stage. Earlier this year, a number of separate reports have suggested Apple was working on a new Apple TV with A5 CPU (the same of iPad 2 and iPhone 4S) to enhance the device’s processing capabilities and allow for full 1080p playback. The current Apple TV model packs and A4 processor (iPad, iPhone 4) and plays back video up to 720p, but as we know the October 4th event didn’t see any Apple TV updates among iPod, iOS 5, iCloud and iPhone 4S announcements. A rumor from July even suggested Apple was working on a new video format called HD+ to launch this fall in the iTunes Store alongside a new Apple TV model.

According to a code string found in iOS 5 by 9to5mac, a new AppleTV3,1 is in the works, and it should be an updated version with upgraded internals such as the aforementioned A5 processor. The existing Apple TV model is referenced as AppleTV2,1 — Apple typically uses this kind of references to prepare iOS for upcoming devices. References in the iOS filesystem are never 100% accurate, but new devices found in the past through code strings have turned out to be real most of the time.

With Apple pushing towards 1080p video content with the new iPhone 4S camera and AirPlay Mirroring made possible by the A5 CPU, it wouldn’t be a surprise to see a refreshed Apple TV with faster CPU and more powerful video processing capabilities. As a side note, Apple recently started selling the current-gen Apple TV in more European countries.

Earlier today, Apple announced the new iPhone 4S, an upgrade to the existing iPhone 4 with improved A5 processor, new 8 MP camera with better optics, faster download speed on 3G, Bluetooth 4.0, and more. You can read more about the iPhone 4S in our general overview; however, members of the press who were invited to Apple’s media event in Cupertino have begun posting their first impressions and hands-ons about the iPhone 4S. It appears this time around Apple won’t let journalists take photos or videos in the hands-on area — possibly to avoid noise hiccups with Siri, the new voice assistant, shown on video.

Engadget notes the iPhone 4S is faster than the previous model, with faster loading times when navigating between pages and opening the camera application (which seemed faster in the BBC demo of Siri, too). Furthermore, Engadget was also able to test the new voice assistant, Siri:

The most impressive part was the demo of Siri, the new assistant that lets you do just about anything you can do on your phone — but with your voice. We tried to psych it out with a bunch of random requests, including the history of Chester, Vermont (a lovely town) and the best Ramen places in San Francisco. Siri never faltered, never missed a beat. It worked as well as Scott’s demo up on the stage. There’s nothing better to say than that. We even sent ourselves a few text messages, which Siri transcribed to a T. Of course, the lady on the other end still sounds eerily robotic, but we’re hoping for smoother responses from the alien within in a future update.

Jim Dalrymple at The Loop covers the differences in antenna design:

What is a bit different are the number of black bands that are on the iPhones. The current model has three bands — one on each side on the bottom, and one on the top. The iPhone 4S has four bands — two on the top and two on the bottom.

The bands are where Apple houses the antennas for the device. The Wi-Fi, wireless and Bluetooth technologies use these areas. It’s not clear at this point if Apple moved any antennas or what they added the extra band.

Slashgear was also impressed with the speed of the new device. The website writes “there’s no lag to be found” when switching between apps, and “webpages rendered instantly”. Similarly to Engadget, first impressions with Siri are very good:

Siri is arguably the main draw. Apple’s new voice-control assistant, Siri makes promises that we’ve learnt to be wary about over the years, but after a brief test we’re surprisingly impressed. Easily activated, with a new microphone icon on the regular on-screen keyboard, Siri managed just what it did on-stage during the keynote. We could ask it local information, such as the weather or to find nearby stores, while online searching and complex questions for Wolfram Alpha were handled with little delay. Speed can be the killer for services like this – people just won’t wait if their phone takes 30 seconds to look up an answer – but Siri delivered in just seconds.

The iPhone 4S will be available on October 14th in 7 countries (US, Canada, Australia, the UK, France, Germany, and Japan) with pre-orders starting this Friday, October 7th. Apple has decided to keep the 8 GB iPhone 4 and 8 GB iPhone 3GS around at lower price points, and will release the iPhone 4S in 22 more countries on October 28th. (more…)

DigiTimes is today reporting on claims from industry sources who say that Apple has signed a partnership agreement with Taiwan Semiconductor Manufacturing Company (TSMC). The agreement will see TSMC produce the A6 chip as previously reported but also the A6’s successor, presumably dubbed the A7.

It now means that Samsung is no longer the exclusive manufacturer of chips for Apple’s iOS devices, which could be related to the current legal battles between the two companies. Sources have also told DigiTimes that TSMC has secured a favourable price, with little impact on TSMC’s profitability.

Apple and TSMC, however, have not yet talked about backend manufacturing, the sources said. It is likely that Apple will have TSMC and the other dedicated packaging and testing house split the orders due to TSMC’s limited available capacity for backend services, the sources speculated.

In reporting about today’s allegedly “leaked” iPhone 5 design per Case-Mate’s product pages (later pulled), The New York Times’ Nick Bilton says an announcement of Apple’s next iPhone is “just weeks away”.

We’re just weeks away from the announcement of the new Apple iPhone 5, according to an Apple employee who asked not to be named because he was not allowed to speak publicly for the company.

Bilton then reports that according to descriptions he’s heard from Apple employees, the images posted today by Case-Mate looked “potentially authentic”. The cases indeed seemed to show an iPhone 5 in line with recent speculation surrounding the new device such as tapered edges, and thinner form factor. In the same article, Bilton mentions “an engineer familiar with the new iPhone” said the iPhone 5 would look “fairly different” from the previous-gen model. According to the engineer the iPhone 5 will feature an 8-megapixel camera as previously rumored, the faster A5 processor also seen on the iPad 2, and possibly NFC functionalities for mobile payments. NFC on the iPhone 5 was rumored before, too, but most recent speculation indicated Apple might save the feature for a future “iPhone 6″ next year.

As I’ve written in the past, two people with knowledge of the inner workings of Apple’s next-generation iPhones say either the iPhone 5 or iPhone 6 will include a new chip that is made by Qualcomm.

Plenty of rumors posted in the past months failed to indicate whether Apple will soon announce a completely redesigned iPhone 5, and iPhone 4-like device with slightly improved specs, or both to address different market segments. You can read more on this in our iPhone 5/4S rumor roundup and retrospective. [image via]

Last month a flurry of reports suggested that Apple might release a new model of the iPad that would be targeted at ‘Pro’ users and featuring a Retina display – many dubbed it the iPad HD. That suggestion (or at least the schedule) seems less reliable today with Taiwan Economic News citing sources within the chipmaking industry that claim the A6 processor won’t be available until at least the second quarter of next year with trials of the A6 only just beginning in earnest now.

Taiwan Semiconductor Manufacturing Co., Ltd. (TSMC), the world’s largest semiconductor foundry by market shares now, has allegedly started trial production of the A6 processor in cooperation with Apple Inc., with the production design to be taped out in the first quarter of next year and scheduled to be publicly unveiled in the second quarter at the earliest, according to industry sources

As previous reports have noted, Taiwan Semiconductor Manufacturing (TSMC) is producing the A6 chip, which would be the central component of the iPad ‘Pro’. The chip is said to be extremely-low powered whilst far exceeding the processing capabilities of the A4 and A5 chips because of a new 28-nanometer process and 3D stacking technologies. Darrell Etherington of GigaOm explains that this differs from the previous layered designs because “the 3D stacking tech will allow layers to be integrated vertically and horizontally into one single circuit”.

According to a report by Concord Securities analyst Ming-Chi Kuo relayed by AppleInsider, Apple may not release an updated model of the Apple TV in the third quarter, instead focusing on software updates to extend the AirPlay features of the device and make it compatible with the upcoming next-generation iPhone. Earlier this month, AppleInsider reported they had been hearing rumors of a new HD+ format for movie content set to bring full 1080p capabilities to a version of the Apple TV. Such new Apple TV, according to “people familiar with the matter”, would run Apple’s latest A5 chip to bring the necessary horsepower to play 1080p movies without playback issues. However, if Ming-Chi Kuo’s industry checks are to be believed, it appears Apple may instead roll out new version of iOS for the Apple TV, rather than a hardware refresh.

Looking ahead to the second half of the year, Kuo said his industry checks have turned up no evidence that Apple plans push a hardware revision to the Apple TV into production during the third quarter. Instead, the Cupertino-based company will reportedly take a more measured approach to advancing the platform in 2011, relying instead on an Apple TV Software Update this fall that will allow devices such as the iPad 2 and upcoming iPhone 5 to beam their content to the big-screen.

Apple doesn’t disclose exact sales numbers of iPod touches and Apple TVs, but Ming-Chi Kuo believes the company sold approximately 480,000 units in the second quarter. In the past months, the second-generation Apple TV has proven to be a successful “hobby” for the company: whilst Tim Cook at the Q3 earnings call said they still don’t consider the Apple TV “another leg of the stool”, in the first three months of availability the Apple TV sold over 1 million units, with allegedly 2 million units placed by April 2011. Meanwhile, similar Internet-connected devices failed to capture the attention of the market partly because of non-competitive prices and lack of streaming features — whereas the Apple TV can stream movies and TV shows using iTunes, and can be integrated with iOS devices thanks to AirPlay. Apple is indeed baking a new feature into iOS 5 that will allow users to beam the full contents of an iPad’s screen to the Apple TV, thus making it an interesting solution for wireless gaming and business presentations. Most recently, Netflix CEO Reed Hastings said the Apple TV was “more important” for them as Netflix keeps expanding to new devices, and an experiment by Mac Mini Vault successfully managed to host a webpage on a jailbroken Apple TV 2nd gen.
