Evasi0n Updates: Version 1.1 Bug Fixes, iOS 6.1.1 Beta Doesn't Yet Patch Jailbreak Holes
Users had reported a number of issues with the jailbreak, including slow boot times and the Weather app crashing, and iPodNN notes that both have been fixed in the update. Other issues do, however, remain, including some users being unable to access their App Store 'Purchased apps' history, and thus being prevented from re-downloading any apps lost or removed from the device.
Jailbreak author pod2g has also noted on Twitter that Apple's just-released iOS 6.1.1 beta does not yet address any of the bugs used by evasi0n in the jailbreaking process. This may change in future betas, however, and evasi0n is not currently designed to work on iOS 6.1.1, so users interested in jailbreaking their devices should hold off from updating.
