Take note that the dev-team’s official stance on the iPhone 3.1.3 OS update is “skip it” unless you’ve had battery problems (the update offers little more). If you wanted to go ahead with the update anyway, this new version of the PwnageTool (3.1.5) will help you safely upgrade your jailbroken device.
Be sure to read the full dev-team post for details concerning your model before diving in. PwnageTool 3.1.5 is a free download for Mac OS X only.
