I have a sprint tour unlocked to a att it says now that i have no browser configuration service book entries the tech guys at att sent the service books no luck
you can send service books to the device from the bis site. was the resent they didnt go through is because its still affiliated with a sprint account. there is a way to activate the legacy service books on the phone, if you google search "legacy service books blackberry" it will generate the browser service books and you will be able to use them. there a few good step by step i have seen from the google search.
