Greetings, I'm buying a P3P this week... I plan to buy a refurb'd iPad 2 mini in another month or so after the iPad mini 4 comes out and the prices for older models drop... I have a spare iPhone 5 that I can reformat and use only for the P3P... since the "regular" 5 is not on the list of recommended devices, will it still work??? I understand it may not be as good as a recommended device but can I get by for a few months???
