Play Store Mexico USA

[elprime]

Hi my name is Miguel, I just purchased a Samsung Tab2 7.0 in the US.

Background. I go back and forth from Mexico to the US very often. I have an iPhone 4 and have iTunes accounts from both countries i buy iTunes cards when ever i need in each denomination, and have both Mexican and us credit cards. Bought the Samsung tablet to have a feel for Android and compare it cus i am about to change my phone and i have not decided yet.
The choices are iPhone 5 or Samsung Galaxy S3 (reason for getting tablet) When configured the tablet i was in Mexico but put the info of a us credit card and when i go to Samsung app store i cant buy anything or even download free apps cus it say the following message. And the apps that i can buy from Play store come in mexican pesos and i want to buy us apps.

"Error

The country information for your account does not match the country information for this store.

-Store Country:
-Account Country: United States

To continue using Samsung Apps, sing in using an account with the same country information as the store"


This are my questions.

1. Can i open accounts in both countries?
2. How do i do it?
3. Is there something like the iTunes store where i can buy music?
4. The music hub does not work it says "Samsung music hub is not supported in this country" i thinks it has something to do with it

Thanks in advance for your help
