I am wondering if this will work with my pocket pc xv-6700 since it has 1.2 bluetooth. The device I am trying to purchase has 2.0 bluetooth but I am wondering did they build it backward compatable to Bluetooth 1.2?

should work perfectly fine... any bt adapter will work with any version device; they'll just communicate at the lowest revision supported by both devices so in this case the adapter will fall back to rev 1.2. just like if you use a headset that only supports 1.1 they would only work at 1.1 specs.
