iPhone software 3.1.3 now available

Apple have released iPhone software 3.1.3 today, available from iTunes. The reported contents are as follows

• 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

Not exactly earth-shattering stuff, but no doubt Apple thought it important enough to push out an update at this time.

Jailbreakers and Unlockers should note that this update will, of course, re-lock your handset to O2. However, those of you with the official O2/Apple unlock will not be so affected (I know, because mine remained unlocked through the update, as it should have).
