BT & mobile VoIP
I've repeatedly tried to run Gizmo VoIP on my Nokia N96 with very limited sucess when inside the house, even with my BT Home Hub on the window (with a sheet of tinfoil 'directing' the signal outwards). the service would drop the connection quite regularly and the quality was poor (echo, delay). I'd be very suprised if any update could turn the HomeHub into a viable phone network. As for web access, there's not much call for 'on the run' web browsing but I suppose it could be viable for running a push/pull mail client?
