For 2 Months I had Treo 650 . When I bought it I played a new soft 1.20 ENA . After few days I saw that my phone isn't good. When somebody calls to me I push the button(red or green ) then the phone is switching off .I don't know what is a problem , but i can't play a old soft to my phone . When I'm trying install a soft version 1.13 , the programm says me that I must push the button on insertion , but I can't do this becouse this insertion doesn't have this button.
