Hi there, I have an odd question, but one hopefully someone here can answer. I'm American but living in Canada. I'm flying to the States to visit my family, and I would like to give my parents two unlocked iPhones (a 4 and a 4S) I previously used. As these items are not new, and I'm bringing them a gift, should I be concerned about Customs giving me hassle? If I read correctly, gifts of $60 can be brought in for non-residents and $800 for residents. Would I be considers a resident living abroad (in Canada)? The worst case scenario is I would be charged some sort of duty for bringing these in? How terrible would that be, and how would they know how to value it properly? Thanks!
