A fix for O2 problems

[Al0uise]

If you are on the 02 network and don't have phone service turn off your 3G then phone service will resume.

Hasn't worked for me unfortunately but thanks for giving me something to try!

Well it has worked now so thanks again!

Bloody 4S doesn't give you that option :(

Mines a 4s and I went to Settings/General/Network then turned off Enable 3g & Mobile data.
