I got my iPhone 4 on Thursday morning and whilst signing up for the new contract gave orange my PAC code from O2. The guy told me it could take up to 48 hrs and usually takes place between 11am and 4pm. Nothing has happened til this morning at 9am when i lost signal in the iPhone 4, followed 30 mins later by my iPhone 3G. It's been over 3 hours and i'm left with two networkless bricks.... Anyone got experience of this? Should i go round the orange shop and harang them? M.
