Fear not, Google didn’t add a #dickbar to Gmail for iPhone. What the Gmail did is actually pretty smart: to better communicate the status of their inboxes to iPhone users, Google recently tweaked the Gmail webapp for iOS devices to include a “connection bar” that displays information for outgoing and sent mail, internet connection, and so forth. It doesn’t appear all the time, it only shows up when a certain activity is triggered – like an email you’re sending from your phone.
It also appears when your phone is offline, back online and sending, and then again when it finishes sending all messages.
You can see the connection bar in action by visiting mail.google.com from your iPhone or iPod touch now, running iOS 4 or later. If you don’t see it, try clearing Safari’s cache in the Settings app. Too bad Retina Display support in the Gmail webapp is still nowhere to be seen.
