As MrW said, it is not available where you are. I and MrW are also waiting for the UK release. Hopefully it will be released tomorrow
As for branding, do the following to check if it is branded or not...
Lock the phone (make sure the screen is still lit up tho), then press the following sequence...
Menu, Back, Back, Menu, Back, Menu, Menu, Back
Then the "Service" menu should pop up. Go into
Service Info, then into
Model Info, and let me know what it says. If it says
Brand: Customized, it means it is unbranded, if it doesn't it more likely to be branded
