Jailbreak

Almost immediately after iOS 6.1.4 was released with a few bug fixes for the Microsoft Exchange data use problem, a new version of the Evasi0n jailbreak utility came out to handle any devices that were upgraded to 6.1.4. It?s still the same Evasi0n jailbreaking experience, untethered and all. Like prior versions of Evasion, the following devices running iOS 6.1.4 are supported: iPhone 5, iPhone 4S, iPhone 4, iPhone 3GS, iPad 2, iPad 3, iPad 4, and iPad mini, and the 4th and 5th generations of iPod touch.

Then why is it that when I try evasi0n 1.5.3 it says it supports iOS 6.0 - 6.1.2? Then I run it and it also says doesn't support this version?

I'm running iOS 6.1.4 on an iPhone 4 CDMA
