Another day, another successful iPhone jailbreak story to report to you. Today, on the heels of purplera1n, iPhone OS hacker "geohot" delivered blackra1n to the masses. Updated.

WARNING: Even though the GeoHot jailbreak supports 3.1.2 do not update if you are on iPhone OS 3.0.1 or 3.0. You will lose your unlock. Use PwnageTool to safely update to 3.1 without performing a baseband update. If you really must have 3.1.2 then wait for the next version of PwnageTool. If you have already updated to 3.1 or 3.1.2 without using PwnageTool then you've lost the ability to unlock for the time being. You can now use BlackRa1n to at least regain your jailbreak
