Written By Sam on 3 February 2010

Apple has released a new firmware update v3.1.3 for iPhone. The new iPhone 3.1.3 firmware can be installed on iPhone 3GS/3G and iPod Touch. The latest iPhone OS v3.1.3 has got minor bug fixes and improvements. Security features updated in iPhone Firmware v3.1.3 are related to CoreAudio, ImageIO, Recovery Mode and WebKit. Most of you must also be knowing that Apple has recently announced the iPhone OS 3.2 for iPad and the current update is not related with that.

iPhone OS 3.1.3 Firmware Update Change Log

  • Improves accuracy of reported battery level on iPhone 3GS
  • Resolves issue where third-party apps would not launch in some instances
  • Fixes bug that may cause an app to crash when using the Japanese Kana keyboard

Currently there is no tool to jailbreak iPhone OS 3.1.3. So if you are on older iPhone OS and jailbroken your iPhone then do not upgrade your iPhone Firmware to v3.1.3. As there were no major feature changes in 3.1.3 firmware it is better to stay away from it if you have jailbroken your device. Do remember that once you upgrade to 3.1.3 you can no longer restore to 3.1.2 unless you have your SHSH on file in Cydia.
