From What Ive seen and heard working in Data Support for Cingular (sorry guys I just work there) Bluetooth can cause PDA's to freak out sporadically....not familiar with the Jabra ...but I know that Crackberries are pick bout what bluetooth devices they pair with .... my ** gives a fake error whenever I do a Bluetooth file Xfer, but the file gets there. Id chalk that one up to being just an anomile.
