Yup, the cat and mouse games goes on.  Its rumored that iOS 6.1.3, that has been released to beta testers, will close the whole used by the jailbreak Evasi0n. This new release is not just to close the exploit keep in mind, there are plenty of other bugs in 6.1 that needs to be address, the issue with MS exchange server memory leak being the greatest.  However, do not fret, the jailbreak teams feel pretty confident they will find a new exploit, just no timeline for it yet.

As such, its strongly recommended that if you are not affected by the Exchange server bug, to hold tight till an exploit to 6.1.3 is released … which is time, Apple will close … and the new exploit will be found.   Good times.
