Apple today has released the new iPhone 3.1.3 firmware for iPhone and iPod touch. This release is just a minor upgrade over the last firmware and it mostly brings stability and bug fixes for iPhone 3GS, 3G, 2G and iPod touch. Interestingly, this (version 3.1.3) isn’t the same version which runs on the newly released Apple iPad (OS 3.2).

If you currently rely on your jailbreak and unlock for iPhone 3G and 3GS, we highly recommend you not to upgrade to this new firmware unless and until new tools are made available from the likes of George Hotz and the iPhone DevTeam.
