To fix widespread 3G connectivity issues, Apple has released iOS 6.1.1 for iPhone 4S. The update is tagged with a build number of 10B145 and weighs just 23MB. The release came almost a week after U.K. and European users reported cellular-related troubles. Many users complained of faster battery drain, 3G and syncing issues, significant increase in dropped calls and lost data connections after installing iOS 6.1 on iPhone 4S handsets. Even carriers had warned customers not to update to iOS 6.1; Apple now has a bugfix release, 6.1.1.
The new release, which should be available through phones or can be downloaded directly from Apple (968MB), is only available for iPhone 4S users. In a support document, Apple says that “This update fixes an issue that could impact cellular performance and reliability for iPhone 4S”. The update, however, doesn’t sound like iOS 6.1.1 does anything to improve battery life as of yet. iOS 6.1 also caused issues for enterprise customers, creating errors around meeting management. The fix is yet to arrive.
Five days back, beta build of iOS 6.1.1 (10B311) was dished out to developers for testing but did not address the connectivity problems but addressed Maps fixes for users in Japan. It is likely that the bugs squashed in iOS 6.1.1 build 10B311 will accompany with iOS 6.1.2 or iOS 6.2 in a week or two.
