so i use to have a treo 600. then i went to the PPC-6700. then i got fed up with sprint so i switched to cingular and got a razr . i had to get another smartphone so found a DEAL on a unlocked treo 650. ive been out of the treo scene for awhile. name some good apps for the treo i should look into getting. i know ill definitely need an app to put custom ringtones on my phone. i think i used lightwav pro for my 600. did they change anything on the 650 that would make it where you dont need a app for custom ringtones?
