I have a Plantronics voyager 520 and a Blackberry Curve 8330 from Sprint.
When I have the bluetooth on and in my ear and the Curve is in my holster which is attached to my belt, every 10 minutes or so the bluetooth will just disconnect (it beeps in my ear) and then about 2 seconds later, it reconnects. However, when I am on a call, the bluetooth stays connected with no problems.
Distance is not an issue because the Curve is always in my holster attached to my belt.
And battery strength is not the issue because I always keep at least half full battery.
I first thought the problem was the bluetooth so i bought a second one (same make and model) and the problem still exists.
So then i tried my girlfriend's bluetooth with my blackberry (she has a motorola bluetooth) and it kept disconnecting.
Is the problem with the bluetooth "radio" that's built into the blackberry?
