I've installed blackrain and unlocked with snow, before I restore my original settings with itunes everything works, after restoring if anyone calls me from the orange network, phone vibrates, no ringtone, screen freezes for a minute then informs me I've missed a call. Costing me a fortune as I have to ring them back!
If anyone has an idea whats causing this and how I can repair it I would be truly grateful as I know alot of ppl on Orange
