iOS 5.1 Beta 3 Released to Developers
iOS 5.1 beta 3 has been released to developers today, the latest build is 9B5141a and is available as a fairly small over-the-air delta update to those currently running iOS 5.1 beta 2. As past iOS 5.1 betas have shown, compatibility is with iPad 2, iPad, iPhone 4S, iPhone 4, iPhone 3GS, and iPod touch 3rd and 4th generations. Registered iOS developers should be able to get the latest build through the Apple Dev Center as well.
Not many new features are known, but reports indicate iOS 5.1 beta 3 gives iPhone 4S the ability to disable 3G and manually switch to the slower Edge network, something that currently isn’t possible on the 4S running iOS 5.0.1. While Edge is much slower, it’s better at conserving battery life and has a larger coverage area, particularly in rural locations.
The first beta of iOS 5.1 was made available on November 28, 2011, and the second beta on December 12, presumably the long holiday break contributed to the nearly four weeks between the release of the 2nd and 3rd betas, but either way we’re inching closer and closer to a public release soon.
