I downloaded a screen saver from the sprint web site for a a cost of $1.50. I have spoken to sprint and they can't figure out how to make it a screen saver and flash when a call comes in or assign it to my favorites. All they can say is that it can be used as wallpaper. The screen saver I downloaded is a zodiac sign representing my birthdate and has a lock symbol next to it. I was able to utilize a screen saver with my 600 that would flash everytime a call came in.....need help....glosaul
