Luketoh, here's the BoxWave link:

You'll note that it's listed as an accessory for the Nokia E62, which uses the same power and mini-USB connectors as the N800, plus (in the USA) the same Nokia AC-4U charger. So we might expect it to be compatible.

However, my miniSync is NOT working as expected. Although the N800 acknowledges the USB connection, on the other side Windows does not recognize the device. And the power tip seems defective, making and breaking contact intermittently as I wiggle it. This leaves me uncertain about whether the USB problem is a real incompatibility or just another quirk of this defective sample.

I'm waiting for BoxWave to respond to my request for an RMA number.
