I have a new Sprint ve20, and I'm trying to find a guide for seem edits (so I can enable custom ringtones), but nothing seems to work. I've got MoST working, and I can access seems with it, but I don't know which ones to edit. It looks like all of the seem editing guides are for other models.
Here's a screenshot of MoST. Note that Offset 000000B8 already has bit 0 turned off, so that's not going to work for the custom ringtone function.
Sprint VE20 has custom Mp3 ringtones enabled out-of-the-box. What are you talking about?
May be something wrong with your MP3s - they should be no longer than 30 seconds, and also mine are at 64kbps rate.
