Hey guys I'm going to need your help here, I am going to buy a used iPhone 5s with around 6 months left of warranty, and i want to know about what else i have to make sure of, besides checking that find my iPhone is off and that my sim card works and make calls? Should i bring my laptop and do a restore through iTunes in front of the seller? Thanks in advance! Edit: Hey mods, can you edit my title please? I meant "im not scammed"
