I'm going to unlock my iphone 4s from sprint with an rsim7 +. I was wondering how do i know what my iPhone 4s is. CDMA OR GSM

You will know if it's GSM or CDMA by which carrier you're with currently:
T-Mobile and AT&T are GSM Carriers

Verizon Sprint, Metro PCS, Virgin Mobile, Cricket Wireless & US Cellular are CDMA Carriers

What would I have to replace to make the conversion? I'd love to tear this iPhone down and replace the needed parts. Already have the tools…
