Apple recently made a new software development kit available to those writing applications for the iPhone. iPhone SDK 3.1 has lots of new tools for developers to take advantage of. Some of the changes include better control over the iPhone’s video editing software which preserves the original recording. Third party applications have also been given access to the video editing software, and the modem software has been updated. iPhone SDK 3.1 also has the MMS feature turned on by default with the AT&T carrier profile update 4.2 included as part of the SDK. Apple has not indicated when iPhone OS 3.1 will be available to end users.
