Apple has re-released iOS 5.0.1 (Build 9A406) specifically for its new-ish smartphone, the iPhone 4S. The device, seen by many as a modest touch-up from the preceding iPhone 4, has been dogged with battery issues from the get-go, with many consumers claiming 10% depletion per hour of the A5-powered device.

Only days after seeding the first Beta of iOS 5.0.1 to developers, Apple today has dropped iOS 5.0.1 Beta 2 to the registered developers of iOS Dev Center.
