What you guys don't realize, is Apple probably won't care if anyone unlocks the phone. They still have a contract with AT&T to provide service to them. If it's unlocked, if anything, they'll just sell MORE units.
This just doesn't make sense to me. One of the major major reasons that I prefer Apples is OSX. So to put Windoze on it just ruins the equation for me. Also, even if you unlock the iPhone and use it on another network, there will probably be some things that just won't work, such as Visual Voicemail.
I'd laugh so hard if Apple and AT&T have some sort of handshake that is required in order to make the phone work, and these people are trying to unlock it only to find out it's all for nill. But then again... I've done things "just because I could" also, so who am I to talk.. heh
