i have this kind of problem, my gsm card already activate for BIS (Blackberry Internet Service) when i put into the phone, already try to register device to network using Host Routing Table, but after register to network, i do not receive any notification, and the gprs is still in small letter instead of GPRS (this is when the device already successfuly registered to BIS service)
but if my simcard is put on other device it can register to BIS easily and i get "GPRS" instead of "gprs"
also already make new user account on blackberry site and my PIN is accepted, try to send service books, but my 8820 does not receive service books
so anyone has knowledge on how to register blackberry to network so it can be activated on BIS
or this handheld of mine is broken? i already tried to upgrade to the latest OS 4.5
