Remember the launch of Gmail for iOS? You might even have it if you were quick off the mark at the start of the month. But more likely, you heard it was available, then pulled from the App Store. Well, Gmail for iOS is back and available for download, this time for the long haul.Google confirmed the reappearance on its official blog. It also confirmed the reason for the original version being pulled: 'Unfortunately it contained a bug which broke notifications and displayed an error message, so we removed it from the App Store. We’ve fixed the bug and notifications are now working, and the app is back in the App Store.'So a happy ending if you have an iPhone, iPad or iPod touch running iOS 4 or above. The company has also addressed the criticism of the original app – check out the feedback and you'll notice a generally poor response to the Gmail app. According to Google, they are 'just getting started with the Gmail app for iOS', so requests for everything from multiple account support to improved notifications and mobile specific signatures are likely to be added in future updates. Google has apparently already improved handling of image HTML messages, so they are now sized to fit to the screen, with the option to pinch to zoom in.The app also offers those push notifications and sounds, enhanced search, auto-completion of addresses, easy photo uploading, Priority Inbox, threaded conversations, archiving, labels and if you used the iPad version, a spilt screen view of your mail. So worth a look if you have a Gmail account and an Apple device, especially as it's free and now functioning correctly.
