iPhone 'partial' unlock

Coders at the iPhone Dev Wiki (not linked for bandwidth concerns) claim to have circumvented some of the locks placed on the device by Apple and AT&T. Buying the product normally requires a two-year, iPhone-specific contract, a move which has drawn critcism mainly for the $175 cancellation fee. But by using a program called iASign, users can liberate the phone for use with existing SIM cards registered under AT&T or Cingular, and possibly MVNOs on the same network. This could be especially useful for those on corporate AT&T plans, who can use a company SIM card and enjoy significant discounts.

Because iASign generates an activation PLIST based on the iPhone's Device ID, CCID and IMEI information, users may have to engage in some research before they can properly unlock their service. Contributors to the Dev Wiki continue to work on a means of unlocking the phone for any carrier, but report that the phone is extremely well-protected, having a maximum number of unlock attempts and a unique Network Control Key for each unit. Even for-profit companies such as Uniquephones have not succeeded in creating a foolproof unlocking technique.

    I thought...

    that once you activated the phone, you could use any SIM card in there. Isn't this true?

    If so, then why not stop wasting the time, activate the phone with 2 year plan with AT&T, then call back AT&T the next day and cancel it (three days to cancel, I believe, sans fee), then you've got a phone that works, plus ready and willing to accept SIM cards.

    Oh, and the wiki is at I believe, so let's go s**** up their bandwidth!

    You are wrong. You can only use the SIM included with the iPhone in the iPhone. You can also use this SIM in other ATT/Cingular phones, but you cannot use any other SIM in the iPhone.
