Can the BB 8703 send a contact to another phone via bluetooth? I was trying to do this with a friend’s phone. His Treo was able to, but my BB didn't seem to have that functionality.

I was later playing around with my Sanyo Katana 2 phone, and I noticed I had this bluetooth capability to send a contact to another phone, by searching for other bluetooths phone nearby.

Can't do that on a BB.

you can however email the contact. and if you wish to another blackberry you can PIN it as well

If you're going BB to BB, you can also send the contact info via Blackberry Messenger.
