Comex the developer behind the JailbreakMe tool has joined apple and currently he is doing an intern with them. He also clarified that he will now answers only the questions to their users regarding the jailbreak but will not help in further development of the jailbreakme updation.
In June 2011, Comex began showing teasers on the JailbreakMe site: it was updated to display a skiing photo including a signboard which said “PDF”, and later it was again updated to display a list of commits that Comex has made to the software.
On July 2, 2011, a JailbreakMe 3.0 testing beta was accidentally leaked to the public a pre-release buggy version that could only jailbreak firmwares 4.2.1-4.3.3 on non-iPad 2 devices. On July 4, the JailbreakMe website was again updated, this time saying “We’ll be back soon.” Comex said on his Twitter account that he was in a hurry since Jailbreakme 3.0, or “Saffron”, was leaked, and that it would only support 4.3.3 at launch. He then tweeted other firmwares may be available in the future.
In the early hours of July 6, 2011, Comex released the jailbreak. The updated JailbreakMe site features a look similar to downloading an App Store app. Instead of there being a “Slide to Jailbreak” slider, there is a grey button saying “FREE”, which turns into a green button with the word “INSTALL” when pressed once, much like any application on the App Store. After tapping “INSTALL”, Safari closes, the Cydia icon appears as a new app, and the device is now fully jailbroken with no reboot necessary.
