Hi

my iPhone 5 fails call. Everytime I make or revive call,  after 15 mins my caller gets cut off, I believe it's due to a iphone 5  fault, I have iPhone 4s and iPhone 3G and there work fine

Op does it only happen on London bridge?

Hmm I haven't experienced this cutting off fault yet:(

Does it happen all the time fletc no matter where you are?

Yes. But not every call. And it does auto redial str8 away. May be iOS 6 issue ?

I'd imagine so. Try restoring your iPhone from iTunes again.

I'm not getting any issues like that so it might fix it:)
