MEGAUPLOAD - The leading online storage and file delivery servicedancedroiddancedroid

Can you please advise on what region/language this is? And provide directions as to what to do with this file?

More importantly, how does it perform? Does it run well? How does it cope with tethering and Flash display?

Many thanks.

this is still very buggy- some improvements but some basic stuff will not work- 3G for example...

That is for XT720(Korea)
