Apple has announced today the official release of iPhone OS 3.1.3, bringing with it a trio of minor fixes, including:
- Improved accuracy of reported battery levels on the iPhone 3GS;
- Resolved issues where certain third-party applications would not launch in select instances;
- and resolution to a bug that could occasionally cause an app to crash when using the Japanese Kana key set.
Users who have jailbroken their iPhone, however, should be aware that the new patch is not compatible with PwnageTool or redsn0w. The tools’ creators, the Dev Team, have released a warning to this effect:
WARNING! At 10.30AM PST on February 2nd 2010 Apple released the 3.1.3 version (7E18) of the iPhoneOS.
If you care about your jailbreak and unlock, don’t update your device – 3G and 3G(S) owners should pay particular attention to this warning.
