Here are 2 different types of Micro SIM from O2. http://flic.kr/p/8fgmiE Note the difference in the size of the circuit.
I've been using the Micro SIM with the larger circuit. It was given to me in the O2 store when I bought the iPhone. Like many others, I'm getting the 'No SIM Installed' error message. The SIM with the larger circuit makes contact with the metal iPhone SIM holder. Is this the cause of the problem, does is short the SIM out?
I've just swapped my number over to the other Micro SIM with the smaller circuit (O2 posted me this one for registering my interest in the iPhone 4).
