I am contemplating buying a Lumia 900 unlocked. Being I have to pay off contract for the Lumia 900 I thought I just might as well get a unlocked version. Does anyone know yet if the unlocked international model will support AT&T's 3G networks, and T-Mobile USA's 3G bands fully? Also what about HSPA+?
There aren't any specs for the international model yet. I would think it would support at least AT&T. If I see them I'll let you know.
I plan on getting a Nokia 808 next as my primary phone. It has pentaband and will support AT&T and T-Mobile. Later on in the year, I plan on upgrading my HTC Trophy work phone to an International Lumia 900, so I'll be watching for it.
