My iPhone 4 has no 3G, edge or visual voicemail. I can only get on the internet using my wifi.

I've tried:

resetting network settings
latest ios updates
creating a backup, then deleting file '8218978e4ab0a48035bb92653145a6be872ea858' from the backup folder and restoring (as suggested in a macrumors forum)

The internet tethering is constantly searching and never stops which I believe may be decreasing battery life.

This is my second iPhone 4, my previous one had the same problem and was subsequently replaced by O2.

I can only presume it could be my sim, but is that likely?

I've read other people have had these issues, but not all simultaneously.

Am I alone here, is there a fix????

Thanks for any help in advance
