I was trying something out with my Instinct and my MacBook. Since both use bluetooth, I had my MacBook search for a bluetooth device. Sure enough, it found my Instinct. Cool. So I tried transfering a MP3 file via Bluetooth from my Mac to my Instinct. It appeared to complete but when I went to run it, my instinct freaked out and said it couldn't play the file or that it was corrupt. So where do I go on my Instinct to delete this "corrupted" file? I see no place to go. What else can I do with this connection?
If you connect with the bluetooth browser on the mac, you should be able to view and delete the file from there (but it is a lot faster to put the memory card in a usb adapter). You should also be able to send vcard contact info to the phone over bluetooth.
Vcard is a standard for exchanging contact info: http://en.wikipedia.org/wiki/VCard. Many computer programs can import or export them and when you send them to the phone over bluetooth they go directly into contacts.
