JAR! Avast ye scurvy 2.0 firmware and prepare to be unlocked!
Didn't take long, did it? Well, actually it did -- the iPhoneDevTeam has been hax0ring away at it since the SDK went wide and Apple, in an attempt to woo legitimate developers, made the beta 2.0 firmware (all 8 versions of it), widely available.
Their latest, release version 2.0, Pwnage tool hasn't gone public yet, but will soon. Are you willing to unlock? 22 countries are getting the iPhone tomorrow, and 50 more are following, but with Apple's tight control of the SDK, my bet is there will still be a few folks out there who want to run anything they dang-well please on their iPhone.
