Jailbreak 4s on 6.1.3 ??

Nope, and its very unlikely there will be for ther rest of iOS6
The devs are reluctant to burn out exploits for every iOS revision. Next JB will most likely be iOS7

Why ppl's keep buying iPhone's is way beyond me.. They dedicate so much time and effort into locking down your phone after you fork out way too much cash for it...
Why not UPgrade (lol) to SGS2,3 or 4? They whip the iPhone's IMO and Samsung (Purposely I think) make them very easy to Root...

What is even more of a mystery is the people who want to jailbreak finally get a release, then a week later accept an iOS update leaving them with no jailbreak haha, madness
