Can someone please tell me what it is that I need to purchase in order unlock for domestic use my iPhone 4s that was purchased from a CDMA network? You might not have heard of it because it's a regional carrier. Open Mobile which only operates in Puerto Rico which is a US territory. I want to know how and if I can use the GSM capabilities of this phone domestically as in using it with another carrier in the US. The phone is unlocked internationally but that is as far as I know.
