Here is an interesting story. I got into an argument with a kid today. The reason? He clamed that the iPhone works with verizon. I laughed and asked how this was possible, he said "I'm buying a stelth sim." I asked what it did, he responded " It takes a Verizon SIM and makes the iPhone think its an ATT SIM." I proceeded to ask if he has ever in his life seen a verizon SIM. He said yes. I said that's impossible. So he pulls out his phone, takes the battery out and pulls some card out of his phone. Guess what it was? A microsd card. He thought it was a SIM card. He clamed it was the new Mini SIM ATT was using, but for verzion. I then went into an explanation that the iPhone runs on a GSM network and verizon uses a CDMA network. He still doesn't understand and is going to try and buy a "stealth sim" and make it work with a microsd card in a iPhone 4.
