Is their an IOS 6.1.3 jailbreak for iphone 4s?

I have an iphone 4s but i'm looking forward to jailbreak it, is their a way to jailbreak it or not?
also does anyonw know where i can get ios 7 beta in case i can't jailbreak it?

Sorry, u r doomed. Only iphone 4s 6.1.2 can be jailbroken. But iTunes won't let it downgrade. U probably have to wait for iOS 7 to be jailbroken when it gets released.

-iOS 6.1.2 is the last jailbreakable OS for iPhone 4S
-iOS7 beta isn't jailbreakable and currently is only available to those who have registered their UDID with a developer account
-Whenever iOS7 releases (probably September or October), there will be an evasi0n untethered jailbreak too (I can confirm it)

An advice to you
Don't ever upgrade to latest OS as soon the OS is seeded. Just wait until users review it and devs make sure it is jailbreakable

There's no jailbreak. As for the iOS 7 beta, you won't be able to install it unless you register your device's UDID with a developer account through a site like http://www.udid.in/.It's $5, and then you don't need to worry about Apple disabling your device for running unreleased software. That's where I registered my 4S.
