iPhone 4 and iOS 7 - Trouble? How to go back to iOS 6
UPDATE: Read => http://www.mobot.net/iphone-4-ios-7-keyboard-lag-fix for the
keyboard lag fix.
There seem to be a few iPhone 4 users out there who regret the jump into iOS 7 waters - "UNUSABLE", they cry...
A couple of Mobot visitors reported "No issues" on their iPhone 4 oldies, but still...
It seems the main 'culprit' is serious lag when using the keyboard and a rapidly
depleting battery - with added heat generation thrown in for pure joy.
Not good at all.
So, if your iPhone 4 is doing well with the new OS, count yourself lucky.
If not (or if you hate the iOS 7 looks and features), head over to this fairly
clear guide on How-To return from iOS 7 to iOS 6.
