Did you try just deleting them off with bitpim? Not just adding stuff on to the phone just delete them and just burn those settings back into the phone?

Thats the same thing that happened to my Audiovox CDM8910. It was like they were deleted, but it didn't free up my memory. I just had to get a new phone, because everything on the phone went down hill after that.

For some unknown reason i can't deleted some of the ringers i put on my phone. Whenever i try to preview them they don't have any audio. I already tried writing over them through BitPim but that didn't seem to work and only gave me an error. Is there anyway i could reset my phone to deflaut memory settings b/c i have everything backed up.
