I'm uploading a Fastboot that already has the chinese radio integrated as well as Mavrick 3.5 with the integrated build.prop and StraightTalk APN added for a hassle free flash. Tested and working on mine and my girlfriends droid 3.
So if you want Mavrick 3.5
Fastboot, Root, Safestrap, wipe all (data, cache, delvik), install zip, wipe all, boot, done.
(AT&T 3G/T-Mobile 2G should be auto-enabled, Straight Talk you will have to select the APN from the list)
