hm...on my Mogul, i can play full length songs on the profile. So far, the ONLY time it will play songs is if they have the Profile Song from
www.westsidemusiccodes.com for some reason, whenever i have a song on my profile from this link it plays it perfectly on my Mogul. I would imagine the same thing on the 6700. Do a test and add a song to your profile from westsidemusiccodes.com and view it on your phone. Lemma know if it plays or not...it does on mine =)
