BlackBerry Curve 8330

i have a jawbone II and my bluetooth connection fails randomly throughout the day for a few seconds at a time. BUT ...!! .. its not the jawbone. the actual wireless connection turns itself off for 10 seconds and then comes back on again. You see this happen on the phone itself. rarely i actually have to manually turn it back on in the wireless menu. has anyone had this problem? I did a phone wipe and hard reset which did not solve the problem.
