I did a bit more research about the V9 ringtone issue and found a few different schools of thought on the matter of applying MP3's as ringtones.
Seems that the problem many are having of not being able to
apply MP3's as ringtones can be a carrier issue (only accepting MP4's as ringers) or a ringtone issue (incorrect MP3 bitrate, filesize, length).
So aside from what I've mentioned about about using MP4's in place of MP3's, you can try doing the following with your MP3's to see if they work:
1.
Length: no longer than 30 seconds.
2.
Filesize: ringtone should be no larger than 300kb.
3.
Bitrate: Set the bitrate to 128kbps. Some users have found that the bitrate needs to be 64kbps, so this might be dependent on the carrier specs or specific to the V8 models.
I do know that some carriers, such as Rogers Wireless, have locked out the option of Applying MP3's as ringers but am not sure about other carriers here in Canada or in the States. I'm sure there's a hack somewhere to deal with this but I haven't come across one yet. For my phone, I have to set the ringers as MP4's and there does not appear to be a limit to the filesize (one of my ringers is 770kb) nor to length (several of mine are 31 and 32 seconds long).
Hope this helps (the above should apply to both the V8 and V9 models, but again, only trial and error will prove which will work with your particular model and carrier).
