I've managed to get a Nokia 6225 to login to sprint with my laptop using
#777!

Here is how I managed to do it... In the Phone and Modem Options, advanced
tab I placed AT+CRM=2 in the "Extra init commands"..

Additionally I went into the modem driver file and under [3GInit] replaced
AT+crm=1<cr> with AT+crm=2<cr>

DennisPG on the sprintusers.com board helped with figuring a way to get this
to work (via IR)...
