Hello I just got my first smartphone, a treo 650 for cingular. I know with bluetooth I can hotsync and have setup such. I was wondering the following:

1) How can I send and recieve text messages via my powerbook linked with treo via Bluetooth? (if possible)
2) How do I setup having my phone be a bluetooth wireless modeom? (if possible)
3) (THIS IS HUGE FOR ME) Is there a way to see incoming calls on my powerbook and answer and talk with my powerbook... so basically my powerbook is acting as an advanced bluetooth headset. I really want this but do not know if it is possible.

Thank you for any and all input, if you have any other treo 650 and PB BT programs you think are useful please share!
