At this point, it almost goes without saying that if you are planning to jailbreak and/or unlock you should always wait for the green light from the Dev Team. Anyway, due to the recent release of iPhone OS 3.1 we have yet another warning coming courtesy of the Dev Team.
“ultrasn0w users *must* stay away from official 3.1 (incl. betas) until we release the tools for it, or you’ll *lose* unlock!”
Basically, if you are looking to unlock your iPhone at anytime in the future using ultrasn0w then you need to hold off on updating to OS 3.1 beta, and once the final version is released, OS 3.1 (the non-beta).
