original iPhone without SIM not working after 2.1 update

You can't update iphones without SIM cards.

Unfortunately, anytime that software is updated on an iPhone, it won't function as anything until activated with a SIM card. She'll somehow need to activate the phone for it to be functional again as an iPod.

I have an original first generation iPhone that has since been de-activated and used as an iPod when I upgraded to a new 3G. When I upgrade from 2.02 to 2.1, iTune gave me the error that it could not activate the phone. I was locked out of using it. The phone was in airplane mode before the upgrade. By using the slider to pretend to make an emergency call, I was able to disable airplane mode and it connected to my local WiFi network. I then reconnected it to iTunes. It activated and now works fine. So - do not upgrade in airplane mode.

i did the exact same thing ur g/f did but all i did was get an appropriate pay as u go sim card put it in activate it then just take out the sim card and bingo u have a ipod touch, when u activate u dont need to fill out bank stuff or anything unless it has never been activated...if it has u will just need to put ur email in and password thats all and then dont ever upgrade it again
