No Service on iPhone 4

[ajayvarma87]

My iPhone 4 was working ok, apart from the antenna issue but now all of a sudden it has no service. Im on o2. Its been stuck on no service for over an hour. Iv tried to restart, restore, reboot, switch sim in another phone using adaptor and its still no service. Anyone else having the same problem or does anyone know what to do? Thanks

im in the same position...i turned on the phone for the first time at 5.30....its now 21.55 and i havent had a signal yet. when the phone is locked i see a dialogue box saying "waiting for activation - this may take some time." i know this is normal but should it really take 4 and a half hours?

im also on O2.
