BitPim allows synchronization of Phone Book, Calendar, WallPapers and RingTones and manipulating the embedded filesystem in CDMA cell phones.
Looks like a very good program. I just wish I could use my SGH-A837 Rugby with the program. I've got a lot of pictures/videos on that phone. The screen has went out, so I was trying to find a sort of plug and play kind of thing to retrieve my pics/vids. Please consider adding the A837 and A847 versions of the Rugby. Thanks! :)
