Infamous DVD Jon cannot leave an encryption unhacked. On his web site "So Sue Me" he published a little tool to activate the iPhone without registering with AT&T over iTunes.

As reported the iPhone SIM card is easy to remove, but using another SIM card is not possible. Looking at the pace that hackers succeed in dismantling the iPhone security mechanisms unlocked iPhones may be available soon.
