Computer doesn't recognize my iphone 4 but iphone is charging
I have a Iphone4
but when calling the micro sometimes stops working, so the other person doesn't hear me any more.
I wanted to connect to itunes but
when i connect to a computer (tried a couple pc's and a mac)
the phone is charging, but my computer doesn't find the iphone (doesn't show up in My Computer).
This used to work before,
and when i plug in my old iphone the computer finds it without a problem.
I removed itunes and installed it again.
I did the resets (7 sec and 20 sec) but nothing seems to work!
What to do?
I guess it's a hardware defect,
if i turn it in they can see it's jailbroken (i can not reset it cause i can not sync).
Can i try 'Reset all settings' and hope they do not see it?
hope you have some good idea's.
