Tethering N800 with two phones?
 

I have a T-mobile Dash and an AT&T Samsung Sync for reasons that would take a bit of explaining...

Ideally I'd like to be able to tether my N800 to both devices. Is that possible? If not, is there a good guide for tethering the N800 to the Sync? I've tried setting up a bluetooth partnership between the N800 and the Sync, but using the AT&T or the Cingular settings it still can't seem to connect.

TIA!
