We’re taking a break from the big game to bring you the news that will make a few stuck Jailbreakers happy. The iPhone Dev-Team released the latest version of their Pwnage Tool application (3.1.5) that will allow you to jailbreak the 3.1.3 firmware.

They are advising anyone unlocked or jailbroken who doesn’t NEED to update to the latest firmware to just let it pass you by. There are really very few “necessary” fixes in the update. There are a couple security updates and a fix to make 3GS battery reporting more accurate. Not all 3GS devices have issues with the battery percentages… ours have been just fine.

The typical caveats apply to this update. If you’re unlocked and jailbroken, you can update with Pwnage Tool so it keeps you at the older modem firmware but installs the new software… it basically patches the older modem firmware into the new software bundle Apple put out on Tuesday. If you unlocked modem firmware 05.11.07 with Blacksn0w previously, you can update with Pwnage Tool and then just re-install the unlock from Geohot. If you’re on an older firmware and unlocked with Ultrasn0w, run Pwnage Tool and re-install Ultrasn0w.

We’d like to agree with the Dev-Team here: if you don’t NEED to update… don’t. Read more on this at the Dev-Team blog via the source link below.
