Has anyone used PDANet on their Treo 180 to function as a modem? My main concern is that I am unable to access secure sites such as my Bank Accounts and even trying to sign in to my email. If anyone knows a solution to this problem, please let me know cause my Treo is my main source for the Internet now, and it is frustrating not being able to visit the sites that are actually important. Also, is their any way to boost the data transfer rate faster than 9.6kps?
