Hi ZammySam and thanx for answering. My V551 has 5mb of shared internal memory. Unfort. no extra memory card for expansion, so when memory gets full i need to remove some stuff. No, though, I haven't relly tried to put in other files into my phone. When I do try to transfer MP3s I do try to transfer the whole file and I put it in, or try to put it in, the music file. i just always get a fail message. Once, though, the MP3 did transfer but when i tried to play it on the phone it said it was an incorrect or corrupt file and that i needed to get rid of it. Do you think I need to somehow shorten the MP3 and if so do you know of any utility that can chop an MP3? Thanx again Zammy for any help you might be able to give.
