Hi all, I was hoping someone would be able to help me with a problem i'm having.

The 3G signal on my 3GS is now non-existent and whenever I turn it on it drops straight to 'No Service'. Before though, even after I had jailbroken it I had a pretty decent 3G signal but now there is nothing. Someone else I know was having similar problems with their signal and restored their phone and that sorted it out, so it might not be a hardware problem.

So what i'm wondering is has anyone else had problems like this and got any tips on what I can do to fix it?

Thanks for your help
