It's an iPhone 4, it's not jailbroken, and it has been working perfectly from release day until today. I can't do anything online using 3G etc. It just says "Could Not Activate Cellular Network". I've tried turning it on and off and tried a reset on the network settings.

Any suggestions? I am using a full miniSIM I've cut to microSIM but it has been working perfectly up until now so it seems unlikely to be the problem.
