So yeah, I m thinking of getting a 6s for my grandad. He doesn't actually need 64gb and Boost has this great promo going on. 449 for 16gb 6S. iPhone unlocks for Boost costs 18.50 on eBay from a reputed seller. So it's a really cool deal. My only confusion is when ( not if) he breaks the phone and i get it replaced by Apple will Apple give me an unlocked one or a LOCKED phone. I am researching on the internet but i get answers from both sides. Anyone here with first hand experience? Are the replacements similar to what we take to them or similar to what was originally bought from the carrier/apple?
