iOS 5.1 upgrade rolled out to iPhone 3GS, iPhone 4, iPhone 4S, iPod Touch, and iPad that addresses battery issue and various bug fixes. Apple March 7, 2012 event is all about The new iPad and iPad Apps, where we also got some cover up to new Apple TV release and iOS 5.1 update that brings SIRI to Japan. There is a need of 189 MB file download to be made via Software Update page on your iPhone, iPod Touch or iPad. This over the air update really reduces the time and saves bandwidth for the users very much.
One of the main concern for iPhone 4S users, is the battery and we hope that this new update will fix the battery issue on iPhone 4S and gives better battery as similar to iPhone 4.

If you have jailbroken or unlocked your iPhone running iOS 5.0 or iOS 5.0.1 then do stay away from this upgrade, as this will remove the jailbreak and you got to wait for some days or months till its available.
