Bluetooth Connectivity

Hey All -
A couple months ago my iPhone went on the fritz with me, it was constantly rebooting, locking up, and just being a major p.i.t.a.

It's since been resolved, I picked through things I didn't need/did need and cleaned up my music library and what not, I rarely get a lock up, but it still does happen. Lately I've been having a major issue with my bluetooth though, and can't seem to figure it out.

When I turn the bluetooth that is paird (it's a Jawbone, I think 2.0, not prime), it takes up to five minutes to actually "connect (hear the beep/status indicator in the phone turns blue), and often times, it doesn't even work at that point. I often find myself talking to no one through the headset, only to find out they were being sent to the phone and not the bluetooth.

Then the bigger issue, when I turn off the headset (when getting out of the car), the bluetooth status indicator is still lit up, and all of my calls are silent, because it thinks there's still a bluetooth connected. So I have to go into the iphone and turn the bluetooth off, and this gets very very frustrating. Then if I go to turn bluetooth back on, it switches on for a milisecond, and then turns off. The only fix I've found for this is a reset, as turning the phone off then back on gives me the same issue.

And in the case that turning the headset off does work correctly, when I go to turn it back on hours later, it takes an extremely long amount of time to connect, sometimes up to an hour.

And the last issue I have (I'm not sure if this is an actual issue or not), is that the bluetooth settings is constantly checking for a new device. I feel like this isn't right, and it might be eating up some battery time.

This is all very frustrating, because I use the bluetooth a lot while I drive, and I was going to purchase a new head unit for my car to take advantage of the A2DP, but I don't want this to be happening all the time.

Any ideas what is going on here?
