I know that there is a software upgrade. It should be available through Palm. But, with VZW, they also have it available on their website. You just have to go to
www.verizonwireless.com then select the "support" tab, choose "phones and devices" under this tab. then from there, select the manufacturer of the phone and press GO, then the phone model. Scroll all the way to the bottom of the page, on the Downloads list, choose "Palm Treo 700w and Palm Treo 700w/x update" option and then just follow directions. -Jessica
