Apple has pushed out a revised version of the recently released iOS 5.1.1. The original public build of iOS 5.1.1 is labeled build 9B206, while this new build is labeled 9B208 (direct download). This is only two builds newer, and probably represents a small fix in the software. Whatever Apple needed to fix was specific to the GSM iPhone 4 (iPhone 3,1) as no revised builds for other iOS devices have been released (perhaps yet). The new build is only available for new iOS 5.1.1 iPhone 4 (GSM) installs and will not be available as an update for users currently on the original build. Apple has not described the changes that are included in the revised release.
