keeping it for a spare.
Not a flame but a question. I too want to save my 1 gen iPhone for a backup. But from what I've heard the SIM cards won't be the same. It would be optimal just to be able to exchange the SIM card and go, but as I understand it that's not going to happen. Is this the case or have I been misinformed if anyone knows?
There is only one type of SIM card. Any SIM card should be able to be put in any GSM phone.
I also sold mine, but debating on not getting the 3G. I might be "over" the iPhone...
