Just picked up my new iPhone 4 today on Orange from Phones 4 U but when i turn it on (with my new SIM in it) it says "No SIM card installed - Insert a valid SIM with no PIN lock to activate iPhone". Anyone got any ideas? The interwebz goes on about jailbreaking etc etc but i've not done anything like that, just put my new SIM in, that's all.
