Unlocked AT&T 820 on T-Mobile?

[gfiz]

Looking at the specs of the 810,820,822, they appear to all have common bands, with the 820/822 additionally having LTE 700, and the 820 also having LTE 1700/2100. Am I reading that right?

Reason I ask, is I was about to drop my remaining 10 months of AT&T and go T-Mo and an 810, but if I could just buy an off contract 820 and use on AT&T, and then presumably get it unlocked in 10 months and use it on T-Mo, I think I might go that route. And if I'm looking at the specs correctly, I think I can?

Would appreciate anyone who is more knowledgeable on these network bands (which is pretty much all of you), to let me know what you think.

After seeing AT&T lock out the L920's T-Mobile band, I'll bet 2 wooden nickels that the 820 is locked too.
