searched it out but no CLEAR answer.

Is there an Mp3 player on the 8700 w/ t-mobile?

If you upgrade the OS on the 8700. Go to T-Mobile to get the OS and upgrade instructions.

so it should work after that??? meaning there would be one?

Yes, you need OS version 4.2 for media on the 8700. Keep in mind that there isn't much memory space for mp3's on the 8700. You may be limited to very small mp3's.

I think the maximum file size per file for transfer is limited to under 3MB, so they will need to be small indeed.

An 8700 isn't ideal as an mp3 player. The memory on the device has already been mentioned, but also the sound quality isn't really up to it.

Given that the quality isn't up to much anyway, you won't lose too much by downsampling mp3s to a lower bitrate. I think that you've got a bit of control over this with the latest desktop software, but not as much as if you were to use something like "lame". Even if you go down to a bitrate of 32 (which is really, really low) then may still need to split some tracks. At that rate a CD rips to 12-18Mb.

Like everyone said, the 8700 isn't a good device to use to listen to mp3s. The mp3 capability is more appropriate for uploading mp3 ringtones to the phone, since even high-quality ringtones are about 400-500kb in size.
