Hi BOAC,
Like Keefer, I am writing this on a laptop connected to a Motorola V3 via a USB cable (that is charging the phone as I surf) and a GPRS connection at 115kbs. (Onspeed enabled to boot!)
I have only had the phone for a few days and it's shown that the Moto bluetooth software is totally incompatible with anything other than Moto Dongles, and as you won't get the phone to charge that way forget about bluetooth for the internet.
It found my old Medion bluetooth headset without problem and that works OK.
The software that comes with it is OK, but the latest update does not function for the diary mode so Moto will need to sort that out.
O2 have dropped the upgrade price to £50 so it's worth going for now. Full price they are £374, so ebay @ £200 is good value.
