A co worker sold me his 6s for $100 today. The issue is he’s on Verizon and I’m on T-Mobile. Will this 100% work? I plan to take it to T-Mobile tomorrow to see. If not, I can just resell it and get my money back. I’m new to iPhones so I’m not sure what all needs to be done, especially since Verizon is cdma. It looks like it should work, but I’m still an iPhone noob. I figured for only $100 it’s worth the risk.
