Legacy RIL requires radio technology equals CDMA or GSM

With the latest update radio technology is set to indicate the type of
network connected (GPRS, HSUPA, etc) and not just CDMA/GSM, breaking
data connectivity for legacy RILs.

Will only affect RIL Versions 4 or below for now, I don't know if later
versions are also affected.
