I'd like to know if I could factory restore my iPhone 4S, insert a SIM card and see if that would make it activated in the other GSM network. The phone was bought from a regional CDMA carrier but they're being extremely shady in confirming whether or not it's SIM locked and if they'd be willing to unlock it for me.
I bought it out of contract and took their service on a month by month basis but it's becoming extremely expensive. Are there any options of unlocking my iPhone 4S (CDMA) to use on a GSM network? And if not, why?
You can see here what iTunes told me after I had reset the phone to troubleshoot a issue and suddenly got the idea but didn't try it because I didn't have a micro-SIM card at the time.
