I`ve got a new phone ( ZTE KIS ) and I`m having trouble getting the music player to work.I`ve got an 8gb micro SD card with some music on it that works fine on my old Nokia phone. Music is downloaded from Windows Media Player so I take it they are WMP / WMA. Should I convert them to MP3 format and try that? There is nothing in the online manual that states what format to use, All help much appreciated.
