Apparently you wouldn't need a BT headset for the 770, however that can be a really nice thing (used them a little bit with traditional cell phones). Any idea whether the 770 would work with most BT headsets out there or would it only be compatible with a limited set of models?
I remember there was an issue with using Bluetooth and WLAN at the same time which obviously will be needed to do VOIP with a BT headset. Does anyone have an update on this issue?
