The newly released iPhone 3.1.3 firmware for iPhone and iPod touch brings bug fixes and more stability for iPhone 3GS, 3G, 2G and iPod touch users. Since Apple has fixed most of the loopholes which were exploited for jailbreaking and unlocking iPhone 3GS, 3G and newer iPod touch 2G and 3G models are currently unjailbreakable until new tools are released. Fortunately for iPhone 2G and iPod touch 2G(older models only) and 1G users, you can use redsn0w 0.9.3 to jailbreak your device on iPhone 3.1.3 firmware.
The newly released iPhone 3.1.3 firmware for iPhone and iPod touch updates baseband to 05.12.01 on iPhone 3GS and iPhone 3G, hence making it impossible for these two devices to get unlocked using blackra1n with blacksn0w. Fortunately for iPhone 2G (the first generation iPhone with EDGE) users, the baseband remains intact. The iPhone DevTeam has just confirmed that their newly released jailbreaking tool called redsn0w 0.9.3 can be used to jailbreak and unlock iPhone 2G on firmware 3.1.3, provided that you have jailbroken it previously at least once.
Apple today has unexpectedly released the new iPhone 3.1.3 firmware for iPhone 3G/3GS and iPod touch. This is not the same version which runs on the newly announced Apple iPad (OS 3.2). To update to iPhone OS 3.1.3 Firmware, all you will have to do is to connect your iPhone with your computer via usb and start iTunes. You should now see a message as shown below. Simply click on “Download and Install” button to get on to the new iPhone OS 3.1.3 firmware.
The folks over at BGR have found out references to iPhone 3.1.3, and the iPhone 4.0 firmware version in their server logs and they seems to be legitimate. While iPhone 3.1.3 will only be a minor release, the 4.0 version certainly denotes a major release version and we can expect it to ship with the next-generation iPhone model sometime in summer 2010. Nothing much is known about about the features that the new firmware is going to offer, but we can expect it to add alot of new features, similar to what was experienced when firmware 3.0 was released.
