Bad news for Windows Phone users on AT&T: if your smartphone is suffering from the “disappearing keyboard” issue, it looks like you won't be getting the fix for it anytime soon. According to an announcement from the AT&T Community Manager, the carrier has no plans to offer the Windows Phone 8107 update to its subscribers. This would make it the second time that AT&T will be skipping an update, the previous one being update 7740.
