Apple has just released iOS 4.3.1, bringing several minor fixes and improvements to Apple's operating system for mobile devices. The build number is 8G4.

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

iOS 4.3.1 is available for the GSM iPhone 4, iPhone 3GS, iPad 2, iPad, and the third- and fourth-generation iPod touch. No update is available for the CDMA iPhone running on Verizon.

Earlier this week, a report surfaced claiming that iOS 4.3.1 would be released with 1-2 weeks, and a follow-up report had suggested that the release might address some battery life issues reported with iOS 4.3, although that has yet to be confirmed.
