For those buyers who wish to use iPhone solely as a media player and Wi-Fi Internet tablet, I have advocated the use of an activate and cancel method to escape AT&T’s monthly charges. My method leaves iPhone functional for emergency calls, and unlike the activation crack, iPhone’s Youtube application continues to work, and I figured that you shouldn’t need to worry that future software updates might return your iPhone to its out of the box, wholly unusable (“bricked”) state.It turns out that I was right. Apple’s recently-released iTunes 7.3.2 update overwrites iPhone’s firmware with version 1.0.1. I installed the update, and even after cycling power on the device, iPhone continues to work exactly as it did before the update.An iPhone with cancelled phone service can still place emergency calls.
