Right.... I took it to the o2 shop. They gave me a new sim to see if that would solve it. But no. Its still not working. Im quite raging because i was planning on using it to get around glasgow using the sat nav app i have on it. Im going down to the o2 shop again early tomorrow morning. If they say i have to send it off im taking it to the apple store in glasgow to speak to them. This is the second one that has gone faulty on me and the warranty still hasnt ran out for the first one!! Im beginning to go off the phones to be fair.
