L920 going to be compatible on T-Mobile?

I was kinda bummed about the L820 compared to the L920, but not enough to switch from T-Mobile to AT&T. I was looking at the hardware specs of both phones, and it seems like they both support the same frequency bands.

That to me says that an unlocked L920 should be able to get at least 3G HSPA+ speeds on TMO's network.

Depending on the price (and availablility) of an unlocked L920, I'll totally try it out. Is anyone else thinking about trying the L920 on T-Mobile?
