I have no advice about buying, not really, but I do have an iphone. The thing is, I didn't purchase my phone/plan on my own, so I don't have advice about plans or what to buy. It's a family plan that I share with my mom,I never see the bills, she gets a discount through the university, and I pay her every month, and she lets me know the rare times I go over (if I call Trinidad which is less and less necessary with skype and whatsapp). I think it's through AT&T (not sure why other than I think that's what my parents use for their t.v./internet). I will say that it's a high quality product (the physical phone). Just like the mac computers I've had at work and at home, I've never had any technical issues. It takes beautiful pictures, too. :)
