Does the iPhone 5 require a factory reset to switch from GSM to CDMA
Before I ordered my iPhone 5 from StraightTalk I explained that I wanted to use it as a CDMA (Verizon) in the US and as a GSM (Vodafone) in Europe.
I specifically asked if the phone would become a CDMA phone again when I removed the Vodafone GSM Sim after returning to the US. The answer was Yes.
The CDMA function worked well in the US and the GSM function worked equally well in Europe.
However, when I did remove the GSM card, the iPhone 5 stopped working.
According to StraightTalk, the only way to return to the CDMA function is to have them do a factory reset, which means loosing all data and downloaded apps.
Of course, nobody told me that when I asked the question.
Does anybody know if this is a requirement for every iPhone 5 or just for StraightTalk phones?
