gprs = in a gprs zone but no IP assigned to your bb
most likely cause you're missing a Blackberry data plan. Do you ever see "data connection refused"?
to get the wap servicebooks, you have to be in "GPRS" and you have to perform a register now via options/security/host routing table/ click & register now. Will not work if you're in "gprs"
try to set the scan mode to manual options/network/ click manual
then do a scan for networks select one you know for sure that has data roaming (ie GPRS) and select that. Cross your fingers
hope that helps even a little bit.
