I have an iPhone 6 from Sprint and it is already paid for. I will be leaving Sprint and selling my iPhone 6, I figured it would be better to have it unlocked before I sell it but not sure so I had a couple of questions:
1. If I unlock it, can it be used on Verizon's (only CDMA I can think of) network? I'm thinking this increase my chances of selling it.
2. Would it be best to contact Sprint before I port my number over to request that they unlock the phone, or after I've already ported over? I've heard they sometimes give you a hard time, especially if you purchased the phone before February 2015. I don't know if it will be harder to do this when I no longer have an account with them.
