Difference between Gratia, Aria, Liberty, Intruder

[Adam_J_T]

So far what I've been able to figure out:
Liberty = code name for device; it applies to all of them.
Aria = AT&T's USA phone.
Gratia = the international version (which uses different 3G bands from the Aria) and is free of AT&T branding on the top.
Intruder = ??

The reason I'm asking: behind the battery on my "Aria", it says "Intruder". I'm just wondering if this means there's a difference in my phone from others.
Thoughts? What does yours say behind the battery?

Intruder was the codename used for the device during development. This was changed to Liberty at some point, but for whatever reason, they never changed the device name underneath the battery.

3G band support is determined by the model number - A6366 for 850/1900MHz 3G bands, and A6380 for 900/2100MHz 3G bands. There's also another version that was sold only in Japan, but I don't know the model number for that.

The A6366 was sold in North America and some parts of South America and was called Aria. The A6380 was sold in the rest of the world and was called Gratia in some countries and Aria in other countries. I think it's only called Gratia in Europe. So, you can't tell the 3G bands the phone supports just by what name it has on it.
