Only a few days after the announcement that the newest iOS 4.3.1 had a working tethered jailbreak, the iPhone dev-team has announced today that an untethered jailbreak has been finalized and will be coming in just hours!

iOS 4.3.1

The untethered jailbreak will reportedly work on the iPhone 4, iPhone 3Gs, iPod Touch 4G & 3G, iPad 1 and the Apple TV 2G using the Redsn0w & PwnageTool software. There will be no iPad 2 support in this release however, because Apple has patched the vulnerability in the iPad 2 (Comex has reportedly found a new exploit which will allow for a 4.3 jailbreak very soon).

Greenpois0n has posted the estimated release times for your city which can be seen here.
