Has anybody been successful in connecting a vpn while using the pearl as a modem? I am on cingular, and following the directions here can connect just fine (very helpful; thank you), but the minute I try to connect my vpn, it all falls apart. I never get an error message or anything, but I lose the ability to send or receive data. Even after disconnecting the phone from the computer, I have to turn off the radio and then back on again to even get data on the device. Any ideas?
