I have had it for about 8 months now on the O2 network.
Recently the phone has been switching off and rebooting during calls

It can happen at any time during a call, sometimes 1 minute, sometimes a lot longer.
Phoned O2 and they said to do a reset using itunes.
Anyone else have an iphone that is/has done this and did a reset solve the problem.
I am a bit sceptical about this but will try anyway.
The phone is still under warranty, should I demand it be changed.
I use the phone for business as well as personal and there is nothing worse than dropping a call when on a business call, has happened twice today
