Sorry for the massive essay... but this issue is really bugging me.
I had an Iphone 4 which worked perfectly fine up until the release of ios 5. It then developed a text stutter on any sms tone, and no matter how many restores from icloud i did, it still wouldn't go away for good.
I took it to the apple store, where they said they have never heard of anyone else having the issue (even though plenty of people have the issue online). They gave me a completely brand new iphone 4, and I hoped that would do the trick. I got it home and found that it was still having the same issue so it couldn't be anything to do with the phone itself.
I have since got a brand new iphone 4s, and thought I wouldnt have to worry about this same issue as it was a brand new phone, with was built with ios 5 in mind. But... I'm still having the exact same issue.
I have tried all the suggestions for a fix, but nothing seems to be working at all (apart from about 12 hours worth of it being fixed).
I wondered if it could be some interference with my laptop or windows 7 itself? Or just with windows interfering with the apple software, because it isn't a mac.
Do you have windows at all? Just trying to find some answers also
