Unlocked Nokia Lumia 920 compatible with AT&T and T-Mobile 4G networks?

Having recently reported how an unlocked Nokia Lumia 920 will not work T-Mobile's 3G network, Expansys USA has listed the same device as compatible with both AT&T and T-Mobile. The listing - as seen below - suggests the unlocked Lumia 920 compatible with AT&T, T-Mobile and Simple Mobile but doesn't list the specify whether it is the 2G or 4G network.
Interestingly, 3G compatibility is shown with AT&T and international networks but not T-mobile, confirming that an unlocked device will not work on the carrier's 3G network. We know this because Nokia's website initially suggested the international Lumia 920 has some penta-band 3G support, operating on the expected 850, 900, 1900, and 2100 MHz bands in addition to the 1700MHz AWS T-Mobile uses as its primary 3G band. Unfortuantely, it was wrong. Nokia confirmed that the 920 does NOT support 1700MHz.
We have reached out to Expansys for clarification and will keep you up to date with the latest developments. If you were planning to grab yourself an unlocked international version of the Nokia Lumia 920 with the hopes of using it on T-Mobile, we suggest you hold on to the thought if you don't want to be stuck with the slow 2G EDGE signal.
