pod2g: Evad3rs not working on iOS 6.1.3 Jailbreak therefore no jailbreak for iOS 6.1.3 (source--iphonehacks)

Apple released the iOS 6.1.3 software update on March 19th. It fixed the Lock screen bug and brought improvements to Maps app for Japanese users.
Unfortunately from a jailbreaker point of view, it also killed the evasi0n jailbreak as Apple fixed 4 security flaws used by the evad3r to develop the jailbreak.
It is currently possible to only jailbreak iPhone 4, iPhone 3GS and iPod touch 4G on iOS 6.1.3. If you accidentally upgraded to iOS 6.1.3 on the newer devices or just bought a device that comes pre-installed with iOS 6.1.3 and are hoping that evad3rs team release a jailbreak for it, then we’ve some bad news.
pod2g, a key member of the evad3rs team has just tweeted that they’re not working on a jailbreak for iOS 6.1.3. They’re waiting for Apple to release a major update.
