The cat and mouse game between the engineers at Apple and the people that provide us with jailbreaks is turning into more of a war than a game. For as long as I can remember, the production of a jailbreak for new devices and firmwares has always had stumbling blocks, but rarely has it thrown as many obstacles in the way as the current pursuit of the A5 jailbreak. We are only eight weeks away from the the iPad 2’s first birthday, and in that time we have only seen an untethered jailbreak possible on iOS 4.3.3 using JailbreakMe 3.0.

Whether or not we will ever see a jailbreak as beautiful as Comex’s JailbreakMe remains to be seen. The simplicity and ease of use of the Safari based liberation removed all of the technical difficulties that some users experience during a jailbreak and opened up the world of jailbreaking to people who had never before considered it. By exploiting a parser security flaw in certain versions of iOS, Comex was able to force Safari to render a PDF then take advantage of a kernel flaw in order to inject the untethered files.

It has now been just over eight weeks since French developer Pod2g revealed that he had found a bug which he believed could be exploited to produce a jailbreak for devs running iOS 5. His theories were obviously correct, with the immediate work beginning allowing the community to benefit from an iOS 5.0.1 untethered jailbreak for all devices running Apple’s A4 processor. This jailbreak is referred to as ‘Corona’ and has been integrated into the Redsn0w tool by the iPhone Dev Team, or is available as a Cydia download for users who are already running a tethered jailbreak.
