Ok its not locked with rogers. I don't think any provider locks bluetooth.
What you have to do is:
Make sure you bluetooth is on and is discoverable. Under settings, bluetooth, pair your phone with the non BB phone. Once that's done good.
Go into media click the menu button, choose explore, go to the file you want. Highlight it hit menu, then choose either send thru bluetooth (to send a file to the other phone) or receiving thru bluetooth (to get a file from another phone)
If this doesn't work then your device may be defective
