i was having the same problem ie being able to send files via bluetooth but not able to recieve them , i was ensuring i was going into the folder i wanted to recieve the file into and pressing recieve by bluetooth before my paired phone sent it and it just kept sticking on waiting for file transfer, i solved it really easy by just rebooting the phone. To reboot just remove the battery on the blackberry while the phone is still turned on , wait 10 seconds and then put the battery back in and turn on, retry and see if this works
