Apple has released iOS 4.3.1 update for users of iPhone 3GS, iPhone 4 GSM, iPad, iPad 2, iPod touch 3rd gen and 4th gen. The update consists mostly of bug fixes, here are the release notes and changelog:
iOS 4.3.1 Software Update
This update contains improvements and other bug fixes including:
• Fixes an occasional graphics glitch on iPod touch (4th generation)
• Resolves bugs related to activating and connecting to some cellular networks
• Fixes image flicker when using Apple Digital AV Adapter with some TVs
• Resolves an issue authenticating with some enterprise web services
If iTunes doesn’t automatically notify you, you can download iOS 4.3.1 by attaching your iOS device to iTunes and then checking for software updates within the app. If you’d rather download iOS 4.3.1 IPSW directly, you can do that too using the links below.
iOS 4.3.1 Direct Download
These are direct download links of iOS 4.3.1 IPSW files from Apple. Right-click and “Save As” to download:
- iPhone 3GS
- iPhone 4 GSM
- Pad 1
- iPad 2 WiFi
- iPad 2,2 (3G AT&T?)
- iPad 2,3 (3G Verizon?)
- iPod Touch 3G
- iPod Touch 4G
Noticeably absent is iOS 4.3.1 for iPhone 4 CDMA. Regarding iPad 2,2 and 2,3, if you own one of those devices and you are directly downloading IPSW, you probably know what you’re doing and know which is for Verizon and which is for AT&T, but I don’t have access to that hardware to confirm either at the moment.
Note for those on Windows: these are .IPSW files, if your browser is saving them as .zip or any other archive, you need to rename the file to .ipsw for iTunes to be able to use the firmware. This is not an issue that affects Mac OS X users.
