Got my 6s plus today. Two issues (one semi-related). First, why the heck won't my phone activate? This is the first time that I went to turn on my phone and no dice. I would swap sims but they always say the new sim is better for some reason. (I didn't use another persons upgrade). Issue two: Why the heck does iTunes pinwheel when I connect my old iPhone 6? It is all up to date but I want to do a backup but it is just unresponsive (computer per my sig).
