PwnageTool 3.1.5 to Jailbreak 3.1.3 Firmware – What You Should Know?

Written By Sam on 8 February 2010

Recently Apple released the iPhone OS 3.1.3 for iPhone and iPod Touch. Many people who had got jailbroken or unlocked devices are facing issues after updating their firmware to 3.1.3. Though there are no major reasons for updating to the 3.1.3 firmware, many people have done it accidentally and are facing issues. Now the iPhone-Dev Team has released the PwnageTool 3.1.5 for Mac OS X which will allow you do so safely, preserving your jailbreak and ultrasn0w unlock.

If you are a iPhone 3GS/3G user and are on unlock please do not get in to trouble by upgrading to the latest firmware. If you make a mistake while upgrading the firmware and then trying to unlock you may find yourself updating to official 3.1.3 in which case you will lose your unlock, possibly forever. If you update your iPhone 3G/3GS to 3.1.3 your baseband will be upgraded from either 04.26.08 or 5.11.04 to 05.12.01 and you cannot unlock it with the current available tools.

If you own a iPhone 3GS then you should stay away from this and all 3.1.3 jailbreak tools unless you know you have your “ECID SHSHs” backed up via Cydia. You can check this from Cydia and seeing that it says “This device has SHSHs on file for iPhone OS: 3.1.2”. If you have your SHSH backup then you can downgrade your phone to 3.1.2 using Saurik’s server and then jailbreak it using redsn0w or blackra1n. If you are not sure of anything that is explained then I warn you again not to upgrade to 3.1.3 firmware.

If you have a iPhone 3G then you just jailbreak on current 3.1.3 firmware. Sadly you cannot unlock your iPhone 3G as the baseband would be updated to 05.12.01. But if you have jailbroken your iPhone 3G using sn0wbreeze, it preserves the baseband and you can unlock your iPhone 3G on 3.1.3 with Ultrasn0w(04.26.08 baseband) or Blacksn0w(05.11.07 baseband).

If you are a iPhone 2G user you can read our guide on “How to Jailbreak and Unlock iPhone 2G With 3.1.3 Firmware Using Redsn0w“.

If you are an iPod Touch user then read the below guides to jailbreak your device.
