So in an attempt to make this iPhone more "sellable" I put the new 2.0 firmware on it. However I was unaware of any new security measures added to the new firmware. Now, it says I can't access the unit unless I insert a sim card. Thing is, the iPhone was attained through unsure methods... we got it as a gift, but we really don't know where the gift giver got it from. I don't have a sim card. What to do now? I heard people on craigslist are offering an arm and a leg to get a hold of even 1st gen iPhones, but did I effectively make this thing unappealing in the eyes of craigslisters since it can't be jailbroken (at least for the time being)?
