If you're like me, you appreciate those little things that make devices different - including different versions of the same device.  We did the Samsung Galaxy S 4 variants, and now, the differences between the AT&T, Sprint, and international HTC One.  The specifications are the same between the models, save for frequency differences (even the colors are identical in this video!).  Diving into the nitty-gritty, though, icons look slightly different, signal strength indicators and LTE logos vary between devices, and more.

Did you spot a difference between HTC One units?  Let me know what you found on Twitter @PhoneDog_Aaron!
