Randy,
If you are an Ericsson fan, no question the handset to get is a T610. It has just about every feature on the planet, a great color screen, a built-in camera, tri-band, and bluetooth. I know several people who have it (including me) and every one of them loves it.
It works well with the Jabra but IMO several of the Sony Ericsson Bluetooth headsets work and perform better. And SE has a ton of other BT accessories (like the RC car) that work with it as well. You can also use it as a wireless modem for your laptop with a USB BT adapter.
Fido is selling the T616 for CAD$400, which sounds really high to me. The T616 is a look-alike that swaps the GSM900 band for GSM850 in NA. It still has GSM1800 for world roaming but you will have a smaller choice of carriers. I paid 120EUR for my T610 from Vodafone (though locked).
Expansys has the T610 for USD$326, or the older but still very good T68i for USD$234. If you don't need the camera and color screen, you can get all of the other features in the R520, which is still my favorite phone ever, for about USD$100. All of these are unlocked and have full Bluetooth functionality.
Personally I would stay away from Motorola BT handsets as they don't have much experience making Bluetooth products yet.
Bottom line if you just want a good phone with Bluetooth, and don't need lots of gadgets on it, the unlocked R520 at $100 is a bargain. It's discontinued now, but has a great screen, good menu system, looooong battery life (like 8 days), GPRS, WAP, and a speakerphone. When I bought mine (one of the first) I paid $900 and was happy.
