Phone tools is nice, but I dont think you get the flash interface or test interface drivers with that one.
Then again, depends on what you wanna do with your phone. All i know the major thing anyone should do on Moto phones is change the gain_table.bin settings to get increased volume, lower the mic pickup gain slightly, increase bluetooth volume output for starters. That alone can help alot. Just becareful with the settings you use, so you dont blow out your speaker like all those on nextel who wanna blast their ringtone over and over on their i730/530
