Good news yesterday was, as we predicted, the launch of Gmail for iOS as a standalone app. The bad news? It lasted around an hour before being pulled from the App Store.But it did actually appear as a free app in the App Store for the iPhone, iPad and iPod touch. When it did appear, the app offered pretty much everything you would expect from Gmail on the go, including those all-important 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. Nothing radical, but most bases covered. Except one perhaps – it didn't support multiple accounts, which many of us have these days. So what went wrong? According to a Tweet from the Gmail team: 'The iOS app we launched today contained a bug with notifications. We have pulled the app to fix the problem. Sorry we messed up.' Which pretty much sums it up really. But according to CNET, specifically that was down to the app failing to appear in the Notifications submenu in iOS 5. Also, you didn't get a notifications entry when you accessed the app from the global iPhone settings menu. Schoolboy errors.So now we're left waiting to see if this is a minor problem or something that needs Google to rip it up and start again. If it's the latter, hopefully someone can sneak in multiple account compatibility too. After all, this is 2011. When it returns, we'll let you know.
