Sources using the latest beta build of the unreleased iPhone 2.0 firmware say that it was recently updated with additional security features. While both versions of the iPhone currently have an "Erase All Contents and Settings" option, it is now known that firmware v1.x (the public software) only does a regular deletion of the information stored on the device. In the 2.0 firmware, sources say that this option will mimic the "Secure Empty Trash" deletion in Mac OS X.
Gizmodo claims to have information from sources within Apple's iPhone software development team that it is "highly probable" that the iPhone 2.0 Golden Master will be completed and ready by this Friday, just in time for a June release like Apple promised us. The final version may launch two weeks in advance of the iPhone 3G. The 2.0 Golden Master release will be following the release of build 345, which added two code-signing and encryption features not previously available.
iPhone Atlas claims to have word from an unnamed user in possession of the unreleased iPhone firmware 2.0 that the new software will have support for both FM radio and FOTA (firmware over the air). We don't know the validity of their information, but if true it could mean that the iPhone and iPod touch will be capable of using Apple's iPod Radio Remote, which contains an FM radio tuner.
