I have the iPhone 4, recently installed ios6 now my phone constantly turns itself off, keeps freezing and then 2 or 3 times in the space of 24hrs it has to be restored to factory settings. This has gone on for over a week.
If all basic troubleshooting has been tried and a restore as new does not resolve, take it to Apple for evalation and possible replacement.
