I brought my old iphone 4 to the apple store to have it replaced due to a defect in the LCD. They gave me a new/refurb replacement with the plastic still on. I don't currently have AT&T service, and so I don't have a SIM to insert to activate. Is there a safe way to bypass this activation? I want to know what ios version is on this phone, but I can't see anything until I activate. Thanks.
