I am looking to purchase an I phone but am having a hard time understanding this whole unlocking thing. Can the new Iphone 3g be unlocked? Also which companies are GSM providers to allow for a sim card to be used in side the iphone? My understanding is that in order to use another company like t-mobile that it is possible but are there any other companies that can be used with the iphone besides at&t and Tmobile?
You have already asked the questions in THIS THREAD. AT&T and T-Mobile. That's it. iPhone 3G is not yet unlockable. That means: iPhone 3G = AT&T. iPhone 2G = AT&T or T-Mobile.
