Hi Thanks for your reply. I have spoken to O2, and they suggested the factory reset, but it won't reset - it just turns off and on again but all my settings are still intact. I have tried 3 times now and still the same result. I tried the radio on an ethernet cable as O2 suggested - still won't work. The alarm function has stopped working - dismiss or snooze comes up on the screen but no alarm sound is emitted.
Now they want me to take it into an O2 shop. They say I can't have another one as I have had it 5 weeks so it has to be repaired not replaced. 5 weeks! I suppose I really am asking a bit much, for it still to be working.
I can see why so many people are buying this just to mod it, if the inbuilt functionality is non-existant, as is O2 customer service...
