No SIM card, need to activate phone
I have an iphone4 with no SIM card, trying to activate it. Is there a way to activate the phone and use it just for itunes. I got a regular SIM for phones, cut it so it can be a micro SIM and inserted it, but it still say no SIM installed, insert a valid SIM with no PIN lock to activate iPhone. I do not want to get a service, just want it activated to use as a iPod until I go back to the states and then I'll go with a service plan.
So how can I activate it? Any help will be appreciated.
