Install Apps which are not available in your country App Store:
We need to follow some steps shown below
Step 1: Launch the iTunes program and, if you are logged in, sign-out of your Apple iTunes account (Store -> Sign-out).
Step 2: Scroll down then click “Change Country” -> select the United States flag.
Step 3: Now search for the name of the app that you are looking to install on your iPad, iPhone or iPod Touch. For this example, let’s try installing Adobe Ideas or iBook (both apps are available for iPhone and iPad but limited to US customers).
Step 4: iTunes will now require you to sign-in with your AOL, MobileMe or Apple ID. Instead of logging-in with your your existing Apple ID, click the “Create New Account” button and accept the “Terms and Conditions.”
Step 5: Use an email address that’s different from the one that’s linked to main Apple account. Under Payment Methods, choose “none” for the Credit Card section, give some dummy address and you’ll then receive a verification email.
Step 6: Click the link in that verification email and you’re done. To recap, you have now created a US based iTunes account and this will let you you can download any free app from the iTunes store even if the app is not available in your country.
We can Install iPhone and iPad Apps from Another iTunes Store
