Lumia 920 does not work on T-Mobile’s 1700 AWS band

According to Nokia's website, the international version of the Lumia 920 will operate on the frequency bands 850, 900, 1900, and 2100 MHz frequency bands along with "strange" 1700 MHz AWS (T-Mobile's 3G band). This is more or less a sensation in the U.S. when the T-Mobile users can purchase a version of T-Mobile Lumia 920 is not "bound" and still use your T-Mobile SIM.

The WPCentral contact Nokia, they confirmed that this is a "bug" because of the fact Lumia 920 does not support the 1700 MHz frequency. Maybe Nokia is to edit the information on the website, but at least at the present time we still see this information on their website.
