Hi, I just got my iPhone 2g that I ordered from ebay, and when I got it today I turned it ON, and apparently I cannot access any of its features without a SIM card? I know I need to unlock the phone so that I can use a T-Mobile SIM card to call people, but I though I should still be able to access all the other features--ipod, safari, wi-fi, etc--but when I turn it ON, it says something like, NO SIM found, please insert one to activate... How do I get around this? My contract with verizon is not due to expire for another month; I thought I could use the iphone as an ipod, and wi-fi web browsing until then, but it won't let me do that... Can you guys please guide me? Please be specific. Thank you very much for you help!!
