A rule of thum is to make sure your MP3s are less than 30 secs and not stored on your card. The card has a hard time 'waking up' and by the time it does you likely will have missed your call. Keep the tones short because it is only going to play for whatever time it is ringing and thus you do not need a 1min ringtone. You do not HAVE to have a card and as PDAPhoneJunkie place your tones in \\Windows\Rings and then go change what tone you want in the notification settings. You can create you own personal tones with various applications. I used to use MP3toRingtone Gold and it was very easy.
