    I unlocked my iphone with the method shown at modmyiphone.com and it works perfectly. As I move forward, I'm thinking what the best approach would be and checked out iphonesimfree's website. They claim that their unlock does not modify the firmware - so what does it do and how does it do it? It seems like their method did not result in a bricking of phones when Apple updated the firmware - is that because Apple targeted the free unlocks, or is it because IPSF uses a method that is less intrusive? In short, is IPSF's method better?

    Since I don't understand what's going on under the hood, please treat me as a complete idiot when you explain. Thanks!

    it's almost as if iphonesimfree had the unlocking code from apple.

    That would be very funny! Maybe Apple gets a percentage from their unlock software sales? All very secret of course, but makes everybody happy.

    Here is the major difference that I know of between the Dev Team unlock and Iphone Sim Free:

    iPhone Sim Free's method generates the key needed to properly unlock the phone. Apple created an unlock method when they built the phone, and iphone sim free's method uses some algorithm to generate a key that will unlock the phone without hacking the firmware.

    The Dev Team found the proper bytes to patch/alter to unlock the phone tricking the phone into thinking it is unlocked, this method is similar in nature to how cracking groups break registration routines in cracked software

    From what you say itsounds like the IPSF method is preferable because it doesn't alter anything? Has this been confirmed by anybody, i.e. that the IPSF methods uses some kind of key to unlock the phone without touching the firmware? If so, it does sound better.

    Hmmm, mine comes tomorrow, so are you saying I should go down the paid method route?
