Less than 15 hours before the expected announcement of a new iPhone model and accompanying iOS updates, Apple has distributed a new build of 10.8.2 (numbered 12C50) to developers that includes release notes, making it likely to be the final version pushed out for testing before release -- which could come as early as Wednesday. The new build comes only five days after the third developer beta and adds a number of previously-announced but newly-implemented features. Also unveiled was a new build of 10.7.5 (11G54).
