Will a used iPhone work as just an iPod?

Question

I'm thinking of buying a used iPhone just as an iPod because they will be cheap after the 3G comes out and I dont have AT&T so I cant use it as a phone. Plus the iPods are still priced the same, hopefully they will change it.

Answer 1

if you unlock it with ziphone you can

Answer 2

A used Iphone will probably function as just an ipod, however the ipod touch has everything the iphone does except the actual cell phone...It's probably a good alternative
