During opening Apple ID. I do not get My country region Bangladesh in given country region list and credit card from my country is not accepting apple. How could I sort it out? I cannot buy any app

There isn't current lay an iTunes Store in Bangladesh, until if/when Apple open one there (we are fellow users, we won't know when that might be) then unfortunately you won't be able to create an iTunes account - you wont be abl eto use another country's store, part of the store's terms is that you have to be in a country to use its store.

Ahh we want apple service in Bangladesh.... pls make one....

As I said above we are fellow users, we can't open an iTunes store in Bangladesh. If you want to leave feedback to Apple about it : http://www.apple.com/feedback/
