I've had an 8GB iphone for a few months now and I use my o2 pay and go sim. I've installed the Edge fix and my Internet on the phone has had no problems at all. Yesterday morning my internet stopped work on the phone, I havn't installed any new applications or anything. The WI-FI still works, but even though the edge symbol is in the top corner of the phone it will not make a connection. I reset the network settings on the phone but this hasn't helped at all and dont really want to be restoring it completely. Anyone else has this problem?
