Is the 6.1.3 jailbreak out yet and when does iOS 7 come out?

Just wondering if the next jailbreak was available yet. I have iPhone 4S. If the jailbreak isn't ready and won't be until iOS 7. Does anyone know the projected release date for that?

IOS 7 won't be released until the fall, but you can install it early if you register your device's UDID on a site like http://www.instantudid.com/.It's $5, and then you can try out the new OS before everyone else.
