Try this:
Pu the card in the phone, and turn on the phone.
Turn the phone back on and remove the card.
Plug back into the computer and look for the music folder.
put all your mp3s in there and remove it from the computer.
Put it back in the phone and turn it back on.
It should now find all of your music.
Good Luck!

try dialing #43574357* it should show you the sid meid min etc. make sure you write down SID. then go to settings from the main menu>press *>587846. in the MIN and MDN field put in 10 digit phone number and put in SID exactly the same as you wrote it down so if 0 is the first number be sure to put 0 and the rest of the numbers. the phone will reset and your phone WILL work
