Vigilant readers over at MacRumors found out the url to the iPhone 2.0 Firmware even before its official launch. After digging through the Apple’s XML files they managed to get the url. This build is slightly higher then the previous iPhone Firmware Beta (5A345) which was spotted on the 3G iPhones.

Be very sure to fully sync before proceeding. You’ve gotta install it on your iPhone manually by holding option key while clicking “Check for Update”,. If for some reason your download is a “.zip” file, rename it to “.ipsw” before proceeding. Make sure you back your iPhone before updating, it will clean up your iPhone completely.
