Im having trouble with the bluetooth on my phone, everytime ive tried to use it to send/recieve ringtones wallpapers it starts but then says failed. why does it do it and what can i do to make it work?

iam also facing the same problem and call log numbers deleted very often

I found out how to work it, switch bluetooth on go to the folder you to put something in and press the blackberry button and choose recieve using bluetooth.

Call logs are often times dumped when the phone's internal memory gets low in an effort to free up space.
