I see people talking about using an unlocked Telus/Bell Storm on Rogers, Could a Bold go the other way? I'm assuming a Storm is GSM and CDMA but I'm not sure.
That is correct. The Storm is a hybrid GSM/CDMA device. The Bold is solely GSM, and can be unlocked for use on GSM networks, but won't cross over to CDMA.
