Hello. My iphone 4, iOS 6.1.3 gone wild....everything is going in slow motion, every app i open is running in frames...i tried reseting the handset, with back-up, without backup(as a new iPhone) and the result is the same. Help ! Apple? Anybody ?

I'm having similar issues just lately. The phone itself is very slow to respond to the touch, just scrolling between home screens is a chore at times. There have been about 2 incidents of random vibration from it. Closing home screen folders takes a couple of attempts. I find that I'm also having delayed keyboard responses when typing messages to my contacts.

Also, sometimes when I press the sleep/wake button it takes about 30 seconds to register it and actually lock or wake up.

Have you experienced the backlight failing to light up? Like if I get a message it flashes up then goes black straight after and when you press the sleep/wake or home button it lights up again but very very dimly and you have to press the sleep/wake button as if locking it and then press it again to bring the screen up properly?

Mine is also on 6.1.3(10B329), model MD245B/A, obviously not Jailbroken, carrier unlocked from Vodafone (but that was months and months ago). Roughly 17gb of storage space left.

This has only started happening in the last 2 weeks. Haven't tried the reset or anything yet though.
