Official Google+ Not Support in Apple Store for Cambodia

I just tried to install Google+ on my iPad with my Apple Store account created in Cambodia address but unfortunately it said something like "this app is not available in Cambodia store (only US), my account could only buy app in Cambodia store of Apple".

So bad for that...
In my Android phone, I have everything but in Apple store, I can't. I might need to search another store to have Google+ on my iPad, I guess.

One big advantage, I want for Google+ on Apple product is with photostream and storage, I hope it will synchronize my stuff on Google+ photos/videos as it does in Android phone.

Google+ for iPad just recently in July optimized and updated for iPad.

I want it!!!!
