Unlock your iPhone 4S/4 for Free - Act Fast!

Unlocking means you can use your phone with another carrier (especially useful when you travel to save on expensive roaming charges) Not sure if this is just a glitch so probably won't last long so head over here to the AT&T unlock portal to unlock your iPhone even if it's still under contact. I recently unlocked my iPhone 4 because it was out of contract (I had it more than 2 years) but now it appears you can unlock your iPhone even if it's still under contract.
