Hi bro, ur uncharted Dual pack R1 got stock?

How much include postage to sarawak?

Got few questions:

1. If i buy it do i need a US PSN account to download those DLC?
2. If so, after i use US PSN to download those DLC, then can i switch to ASIA PSN to play all those DLC and achieve trophies? Or it can be done by using US PSN only?
3. Do you have R3 version for this dual pack?

Please kindly answer above 3 questions, thanks!
