I got Sprint service & my phone iz a Treo. I've been trying r figure out how 2 mp3 file share & share some of my downloads like u pix share 4 the longest. I even called Sprint & the customer service rep didn't know either. The thing iz I've heard that itz some kind of way u can do it thru your blue tooth. I might just be trippin but thatz what I heard. If anyone knows what I'm talkin about & knows how 2 do it post some info.
