iOS 6.1.3 kills evasi0n jailbreak.

6 minggu setelah tool JB evasi0n rilis, akhirnya Apple menutup threatnya di iOS 6.1.3.

Apple has released iOS 6.1.3; do not upgrade or restore (if you want to keep your jailbreak). You cannot downgrade/upgrade/restore to 6.1.2 using SHSH blobs on newer devices (A5/A6 devices); older devices that can use SHSH blobs are iPhone 4, iPhone 3GS, and iPod touch 4th gen.

IOS 6.1.3 is out. Jailbreakers stay away! There’s no coming back to 6.1.2 JB even if you saved blobs (except iPhone4 and ipt4g)
