This same unit that negri sells.. http://negrielectronics.com/motorola...ked-black.html
Anyway, here is what I have to say about it.
I booted it up, and it started in english (i've heard if you get a latin america unit from other countries you have to change to spanish).
Its just like any american unit except made in china. Also I had a XT1053 t-mobile edition that i returned. Mine had a very minor scrape on the bottom back edge, and 2 little plastic defects on the LCD trim (like the one ifixit had on their unit). This chinese unit has none of that.
It also came unlocked, has no carrier branding anywhere or carrier apps. seems to be working ok so far on 4G. Also another nice thing it came with a mic / headset which the american ones don't come with. One other difference, the default background is the phasebeam not that american flag motif.
I suppose that is to make up for the labor costs who knows. So given the sellers on ebay don't charge tax, its about a $100 savings... haven't tried to unlock the bootloader yet but it is on the list, so should be no problem. if you are on at&t and want to save $100 over the xt1053 well this is an option.
also another difference i just noticed which is i guess of the marketing driven lies only in the US.
if you are on LTE on the claro phones it says "4G" in the status bar. if you are on HSPA or HSPA+ it says either H or H+. nice and non confusing.
on my t-mobile unit, it ALWAYS said 4G. with a tiny LTE on it if it was 4G LTE.
