On a related note, the Android version of Instagram was released early this morning. If you’re on Android, download it now!
P.S. Got to experience first-hand the Great Firewall of China. Most blog services are banned (self-hosted WordPress is safe), Twitter + Facebook are blocked as well. If I wanted to post to Twitter or FB, I’d have to use apps like Instagram, Foursquare or Path as these are unblocked. Our local tour guide told us that she really doesn’t feel the need to use these anyway as none of her friends are in it. To her, the mobile phone is more important and China has gone a long way since.
