They're basically the same phone. Maybe 820/822 forum.
But... they really aren't the same phone, at all actually. The 822 is closer to the 8X when it comes to specs. The only real difference between the two is screen resolution, and form factor. Oh and the 822 has expandable memory. Outside of that they are identical.
P.S. I agree with Master Cheif - Give us an 822 forum!!
