There isn't enough to even be concerned with size. I like bigger tires on by truck, so give me the American made phone. (oooo, 3/8 of an inch taller, with a bigger screen, hardly any talk to be had about size, IMO) As for all tires and phones, you can roll, and make phone calls just fine with any of them. The Inc has some beef too, but it is also a great phone, lol. These days, having the latest phone will only last you 2-3 months, get used to it, and get happy with what you roll in, lol.
