[Q] Will the Galaxy S2 asian version work with AT&T's 3G and upcoming 4G?

Hi guys!
New to the forum. I'm about to purchase a Samsung Galaxy S2 in Hong Kong.
I was wondering if this phone will work on AT&T's network, namely their 3G and their 4G frequency. It'll be quite pointless to get this phone if I couldn't utilize it's speed.
Thanks!

Hi - could you help me by mentioning whether 4G LTE is working with you now in Dubai? I am planning to buy an S3 and would prefer an LTE but not sure if it works here !

[Q] U.S.Cellular SIII to straighttalk

Another noob baptismal ... Here goes ,,, I.may soon be the recipient of a Samsung Galaxy S3 U.S. cellular (SCH-R530) ... Of course its locked and I will also be repairing the screen it looks like.
Currently, I have an SCH-720C (Samsung Proclaim) bought from StraightTalk and running on Verizon towers, completely stock. Since both are CDMA units, will it be possible to unlock the S3 and find a way to use that phone on my straighttalk account?
If so, what will be required? Can I plug and play using the Straighttalk sim?
Thanks for the warm welcome.
