OK now this makes more sense to me. Once I got the beta installed and working, it stopped working after a reboot. My problem with an error trying to start data roaming came back again... Then I realized that after reboot if I connect to sprint data, then let the data connection transition to roaming and then start GoodLink, it works again--even after I switch back to sprint. It really has to be data roaming when you start GoodLink. Sounds like a configuration problem on Sprint's side if you ask me.

Anyhow, thanks again for the help! :)
