The iOS 6.1.2 update is rumored to be rolling out sometime next week.
A German site known as iPhone-Ticker is reporting that Apple is planning to release the update at that time and that it will correct the Exchange bug and lock screen passcode issue that has been plaguing users since the iOS 6.1 update was released earlier this year.
iPhone-Ticker has provided some accurate information in the past for iOS release schedules. The site accurately predicted the roll out of iOS 6.1.1 before it was available to the public.
The iOS 6.1.1 software update was released in the middle of last week and corrects an issue that could potentially impact cellular performance and reliability for the iPhone 4S. The problem has to do with the 3G connectivity. Carriers had warned their customers about these issues before they download the iOS 6.1 update.
The iOS 6.1.1 update has a build number of 10B145. It is also 23MB in size.
The iOS 6.1.1 was first seeded to Apple developers last week.
The software update beta came just two days after a major jailbreak was released for iOS 6.1. The beta's build number is 10B311. It is compatible with many Apple devices including the 4th generation iPad, iPad Mini, 3rd generation iPad, iPad 2, iPhone 5, iPhone 4S, iPhone 4, iPhone 3GS, 4th generation iPod Touch, and the 5th generation iPod Touch.
The software build makes some major improvements for the Maps application for Japanese customers. These improvements include better pronunciation of roads during turn-by-turn navigation, optimized directions to more strongly prefer highways over narrower roads, the ability to notify about upcoming toll roads, added labels for junctions, interchanges, on-ramps, off ramps, and intersections, added indicators for transit station buildings, subway lines, and traffic lights, updated the freeway color to green, and updated icons for some location categories such as fire stations and hospitals.
