Individuals who classify themselves as registered developers on the iOS development program will already be well aware that the second beta of iOS 6.1 has been available for past two weeks, but as always, the Apple engineers responsible for the development of iOS have been working hard behind the scenes making changes and improvements to the mobile operating system. The work put in over the last fortnight and the changes and improvements made have now manifested themselves in the form of an iOS 6.1 beta 3 seed to registered developers, available to download from the developers portal.
