Hi, How often should one person change his/her iPhone ?? How long should one expect it to live ?? I still have an iPhone 1, (the first model). Due to short battery life and to restrictions using applications like whatsapp, is that I have purchased a newer iPhone '4S' or '4s'. But the big question for me, is how long should I expect it to live, and how long should I expect it to stay functional? It is a b?tÇh to be changing a phone so often. It has a toll on the planet and things should be made to last and at the same time be cost efficient, (at least, that is something I hear people talking quite a bit). Thank you in advance, kind regards, igmolinav : ) !!!
