A6366 vs A6380

[Ndrd]

There are two models of HTC Aria available: A6366 and A6380, and, as far as I know, the only difference between those two is 3G frequencies:
A6366 supports HSDPA 850 / 1900 (AT&T in USA)
A6380 supports HSDPA 900 / 2100 (worldwide)

Is that correct?

If it is, why there is so many sellers who offer HTC Aria specifying both bands: HSDPA 850 / 1900, and HSDPA 900 / 2100?

Is there a model that support both bands? What is the particular model number of that phone?

Or they simply don't know what exactly they are selling to customers and just copy/paste the misinformation from one place to another?

Thanks
