can I use mp3 file format for my ringtones...what do I need to do in order to send mp3 file to my bb 8700r and set it as my ringtones....thanks everyone!

Yes you can.

Upload them here: http://www.coolservice.dk/en/compatibilities.php

Then go to the download location on your Blackberry using the Internet Browser to download.

Yes - there is an entire forum - not just a thread - dedicated to Ringtones, Themes and Wallpapers. There is a Yahoo group (8700ringtones) set up just for this.

The answer is yes, you can have MP3 ringtones, and you download them via the browser.

Please check the appropriate forum, where there are hundreds of threads about ringtones.

Good luck!
