on some i think yes, but on the scoop they locked it out. they dont tell you this either.

i can put mp3s on my sd card and listen to them but i cant use them as ringtones. howardforums has a hella long thread about people and this issue. you have to get into the system files and do these certain steps to get around alltels lock. only way to get custom ringtones without buying them from alltel.

did not know this before i bought the phone, but not really a big deal. since im usually on vibrate anyways
