Apple updated the iPhone OS software that powers the iPhone and iPod touch late Tuesday. Filed as a minor update, iPhone OS 3.1.3 improved the accuracy of the battery level indicator on the iPhone 3GS and fixed a few bugs and security patches. The 228MB update can be applied to all iPhone and iPod touch models, Apple said. The company recommends the new version due to fixes for several security-related issues.
According to the release notes accompanying the download, iPhone OS 3.1.3 contains bug fixes and improvements, in addition to the following items:
* 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.
The software also contains five security updates addressing CoreAudio, ImageIO, Recovery Mode, and Safari’s WebKit layout engine. The fix for the iPhone’s recovery mode prevents malicious users with physical access to a locked device from accessing the user’s data. More information on Apple’s security updates is available here.
iTunes should automatically notify you about the new software when you connect the device to your computer. Alternatively, you can check for iPhone OS updates manually by hitting the Updates button available under the Summary tab that appears when iTunes recognizes the device connected to your computer.
This update is a free download for all iPod touch users who upgraded to iPhone OS 3.x. iPhone OS 3.1.3 arrives nearly three months after the company posted a previous maintenance update, iPhone OS 3.1.2, in late October. First hints of iPhone OS 3.1.3 appeared in browser logs mid-December. A recent Chitika Research survey indicated that nearly half the iPod touch users refuse to pay $5-$10 to update to iPhone OS 3.x.
