Get them while they’re hot! http://www.iphone3g-mods.com/ (coral) has a great list of download links for all the various hardware versions. There are a couple of notes: First, this is intended for developers only. As such, these FW versions lock your phone into “testing mode,” meaning you can’t then downgrade to an old version. Also, this final pre-release is not jailbroken (rather, it probably is, but the JB is as of yet unreleased). So don’t plan to use this on your main device if, like me, you rely on your jailbreak. I’ll probably only install this on my iTouch 1G, and wait for a proper jailbreak following the official release.
