I bought a new iPhone 4 today from O2. The man in the shop swapped my old sim across to the new micro-sim for me to save me the hassle. I returned home and plugged my iPhone into my PC to sync with iTunes. I went through all the steps and my iPhone was set up with iTunes and had synced my music and everything.
However, my iPhone still says that it needs to be activated, and it says that there is no signal, please help
