I have a problem, Why does Mighty Rom break my .wav files?
I have an "AOL" .wav that I have used for years in every wm device
all I do is copy it to the windows folder then I can set it in sounds and
notifications to my email so when I get new mail it says "You've got mail"
I copy it over it works fine till I soft reset my phone then the .wav file is NG!
If some one knows how to fix this that would be great or I will just flash back to my slow verizon rom atleast it works with verizon.
