I'm not sure if anyone else is having problems with this, but since I've upgraded to Froyo, I loaded two programs (Angry Birds and HumansVsAliens on the SD card...they work great, but adding them to a desktop doesn't work. Any time I turn the phone off and back on, the icons are gone from the home screen...I believe this is because they are installed on the SD card because I don't have a problem with any other icons..
