Providing In-App Purchase, in a free app

I want to submit a free app with In-App purchase in the Appstore which can be available in all geographies and not restricting to any particular geography.

However,I do not have financial account for all geographies,say, i just have a account in US .So, as i am making the app freely available for all geographies but do not have financial accounts for all geographies,how can a user outside US buy any enhancement through In-App purchase? Does Apple restrict such transactions any way? Or, does Apple reject such applications?

Supposedly,If this app gets approved by apple and goes to app store and any user outside US downloads this app and tries to buy any enhancement using In-App purchase, how will the financi开发者_C百科al transaction happen?

I may be way off here but doesnt apple handle all the payment transactions themselves? I thought they processed everything, took their 30% cut then gave the developers their share. If that is case, they probably handle the international transactions and give you your share the same way they would any local transaction. It wouldnt make sense for you to have to have accounts all over the world in order to sell an international app.

Also, I dont believe this would have any effect on weather the app is approved or not. Apple wants as many people doing in-app purchases as possible so they can make as much money as possible.
