BT747 should work on Mobile Phones that supports CLDC 1.1 / MIDP 2.0 and JSR-82 (bluetooth library). Take a look into the list of working reported phones. Please report if you have run it on a unlisted device, so we can add this to the list. Thanks. Download the current stable version from BT747-Sourceforge-page (select the file BT_J2ME_version.zip). Unzip the content and change to "dist".

For a list of known phones, see further below (leave a message in the forum if your phone is not on the list). Here is a first throw at explaining how to get BT747 on your phone!
