Apple patching up iPhone jailbreak

iphone_home11Cupertino is apparently getting into the security business, locking down an exploit that has enabled ambitious users to unlock the previous versions of the iPhone.

Since shortly after the introduction of the first iPhone, development teams have been able to exploit a flaw in the phones OS, enabling them to create a modified OS with the ability to install whichever apps the user wants – legal or not.  This process also enabled users outside of the US to use the phones in their home country (yup – I was one of them!)

The fine folks at mobilecrunch have a great description of the process:

“If you want the full technical rundown of the exploit, you can find it here. In its simplest form: as with all computers, the iPhone requires something called a “Bootrom” to startup. During the startup process, one stretch of code in the Bootrom fails to ensure that the content being loaded is within a certain size limit. By throwing more instructions at that chunk of code than it’s intended to handle, exploiters are able to make the iPhone do damn near whatever they want; in this case, the jailbreaking process.”

Does this mean that the next version/release of the iPhone won’t be able to be jailbroken?  Possibly, but like all other computer systems – if the people that want it bad enough put their minds together, they’ll be able to crack the new code in no time at all.

Good luck to the dev team!
