I landed an iphone 3g 8gb today for 100$, I'm no stranger to unlocking phones but i never bothered with the iphone it but I couldn't pass up this kind of deal. I really dont know what to do with the thing, it was reset so it wants a sim card and itunes and I'm not sure if the phone is legit. So what should I do?

Unlock and sell on ebay.
I bought a 2g for 100 and sold it for 360.
