Can someone please confirm if the unlocked att windows phone 8x will work on Tmobile's HSPA+ network?

The HTC 8X is going to be available on T-mobile , there is no need to buy it on AT&T and unlock it to use it on T-mobile ;)
You can go to T-mobile website and type HTC 8X on the search bar and check, as of today it will show you the phone, the specs and it says coming soon

But the thing is I don't have any upgrades on my T mobile account and I don't want to pay full retail price for that phone. I have an AT&T line eligible for upgrade. Am trying to use my att upgrade so that I can get out of T mobile ASAP.

AT&T will not give up an unlock code easily.
