The system update will NOT flash your radio. I've replaced the radio attachment, it should work now.
This update does not remove any bloatware. It should leave you at a complete stock DI01 system with root and busybox. It will completely reformat /system, so it will work regardless of changes you may have made to your phone.
I've also attached a few apps built from aosp with a few mods. Included are the DeskClock, Gallery3D, Mms and Music apps. They will REPLACE your existing versions so back sure you have a backup in case blah blah.. The Music app is forked from Eliot Stocker's music mod (CM), and the Gallery3D app is forked from code aurora forum. DeskClock and Mms apps are forked from aosp with a few slight mods (black background in mms,etc).
DO NOT put this on your sdcard as /sdcard/update.zip. That's where clockworkmod lives.
