Odd bluetooth realated issue
 

I'm running the stock Sprint ROM and just recently bought a bluetooth headset (BlueAnt Z9i). I've noticed that when I pair up the headset and then initiate a voice dial call through the headset, my phone will switch from vibrate to ring. While that isn't a major problem, it is annoying because I don't always catch that it is on ringer now to put it back on vibrate. I personally like a quiet phone and have it on vibrate most of the time (it is usually on my person at anytime I would be wanting to accept a call). Anyone else see anything like that?
