The "Bluetooth Bug":
1. The N73 (afaik) is only BT 1.2, and thus doesn't support having two devices connected at the same time. I have absolutely no backing for this whatsoever, and will test this theory on my way home tonight.
2. The bug was ONLY with gps units, for some reason. With .01 I could hold a connection to my headset, computer, and other phones no problem. But the gps unit wouldn't stay longer than 3-5 min max. After conversations with Wayfinder, it was decided that the .03 firmware fixed this, so I did it myself, and it did. I'm now able to hold a gps bluetooth connection as long as i want, with everything else constant, so it was indeed the firmware that fixed it.
