First: My blackberry is lagging bad. I will put my sd card in and wait like 10 or 15 seconds and go to look at the music on it and some of the songs and albums will be missing and it takes about 5 minutes to build the list...and half the time it will never actually load the whole list. Secondly when i remove the card and wait...the phone will prompt me that it was removed but all the songs are still there...the media list never empties and my saved photo wallpaper never goes away...this is very frustrating.

It is a 1gb card and brand new.

another thing is that i can't seem to get some songs to play even though they are mp3 format, and not locked or anything, it will just say "the media is of an unsupported format" why woudn't it play the files?
