I've always found Nokia phones to have all the latest features but are usually poorly implemented. All the Bluetooth Nokia phones I've had were terrible. Most of them just crashed or didn't work properly or like the 7650, didn't have the headset profile so Bluetooth was pretty much only for syncing.

Rant over. Yeah, SP2 seems to be a lot better for Bluetooth and WiFi as well. You can finally set a default WiFi connection you want to use if it detects more than one. I've not had the "Hey! I've just detected some WiFi AP really far away with a crap signal. Are you sure you didn't want to connect to that one instead of your AP? I've disconnected from your AP anyway..." problem recently.
