Many people complained yesterday about various problems with the jailbreak solution offered through jailbreakme.com, and this article was made with the idea of explaining some of these problems. It seems that in the initial version of the jailbreak solution, a small error crept into the code that verifies the implementation of the jailbreak solution, and the solution to this problem came only a few hours after the launch, because comex was sleeping and saurik had a hard time figure out where the problem comes from. Many of you tried to jailbreak but got a purple screen, well it was from the small problem of the server and not from the load. Besides that, it seems that the jailbreak solution leaves a exploit open in your phones, exploit that could be used by anyone to control your phone. After waking up, comex fixed this problem and updated the payload of the site including the new fixes so that no one has any more problems. The new fixes also solved the problems that iPhone 4 users had with MMS/FaceTime, but also solved the problem that led to the impossibility of jailbreaking the iPad 3.2.1.
Having said that, my advice is to jailbreak again to be sure that any bugs have been fixed. You can jailbreak over the previous one, I did and I didn't find any problem.
UPDATED : The exploit that causes the vulnerability in iOS has not been fixed, so you need to install it Patch which partially covers the hole.
