What network? I'm on orange and that's been playin about lately thing like gettin 2 of the same txt and receiving ysyd really late :S
Ye my m8 with another iPhone 4 on orange said exactly the same thing as what I have a prob with last night then I also got a load of weird txts sayin turn phone on and off for signal reasons and plus they joined T-mobile so maybe it will get better after today
