Hi, if you have 3.5g coverage in your area, the n800 connected to a 3.5g phone will give you 720kbps. limited by the max throughput speed of bluetooth. Bluetooth 1.2 and 2.0 should not be any different speed wise. This would be translate to download speed of 90KB/s. not slow for me. in fact better than wifi from many heavily populated hotspots.
