I just bought a new Droid RAZR yesterday and also an Elite Flip to go with it.
I got them synched up just fine and the sound quality in the Elite Flip is very good. I can dial out by voice command, but if the phone rings on an incoming call, I have yet to figure out how to answer the phone without having to pick up the phone and hit a button.
A friend of mine has a different phone and Bluetooth, but when his rings, he doesn't have to touch his phone - he just says "answer" and then it answers. Or he can say "ignore" and it goes to voicemail.
I bought this setup in part to get that functionality, but so far I have not been able to figure out how to do it. Is it just not an option with this phone and headset?
