News is extremely limited at the moment, but TUAW reports that another version of the iPhone SDK and iPhone firmware have been released by Apple, and are available now to download. The news is still coming in from the developers that have gotten a hold of the new firmware and SDK.

The new SDK weighs in at just under 1GB. This makes it less of a bandwidth headache for the developers. We are waiting for more details to come in now. Check back as we update this post, with all of the latest details about this unexpected update.
