Fully SIM Unlocked iPhones

Engadget posts confirmation that iPhoneSimFree can provide a software application that will completely unlock the iPhone, allowing you to use other mobile network's SIM cards.

The six-man team has been working non-stop since launch day, and they're officially the first to break Apple's SIM locks on the iPhone. It's done. Seriously. They wouldn't tell us when and how they would release it to the public, but you can certainly bet that they'll try to make a buck on their solution (and rightly so).

Engadget posts screenshots and notes from the install. Some highlights:

- The unlock process took only a couple of minutes
- The General -> Network menu now has an EDGE network settings area where you can input your carrier's APN and username / password
- No Visual Voicemail. (but regular dial in voicemail works)
- The method claims to be restore and upgrade resistant

It appears iPhoneSIMFree will start selling this application next week.

SIM Unlocking the iPhone will allow users to use other GSM-based mobile networks with the iPhone. For U.S. customers, this limits you to simply switching to T-Mobile from AT&T, but international customers now have much more flexibility and could use the iPhone on any GSM network.
