Google+ is the new social network that Google launched yesterday and the invites are already spreading like wild fire. Google also made sure they release an Android app just when they took the wraps off Google+. 
Users in Pakistan cannot download the Google+ Android app directly from the Android Market. The app is available to some countries only at the moment.
NOTE: You need to have a Google+ invite for this app to work on your phone!
