Apple has released iPhone OS update 3.1.3, and along with the bug fixes and security patches comes the inevitable breaking of jailbroken devices.
Creators of jailbreaking tools such as Redsn0w, Blackra1n, and PwnageTool have warned jailbroken iPhone/Touch users to not update to the latest firmware just yet. In fact, Redsn0w was updated just yesterday to work with OS update 3.1.2.
For now, if you want to keep your device jailbroken, do not update to 3.1.3, and be careful with the unpatched security exploits.
