Instagram is now available for Android supporting any phone running Android 2.2 or above (with support for OpenGL ES 2). Instagram is a free app allows you to share pictures with your friends and family and can be easily uploaded to other social media platforms including Twitter, Facebook and Tumblr. Simply snap a photo, then choose a filter to transform the look and feel.
There are a few features available in the iPhone app that aren’t in the Android app - Tilt Shift / Blur, Share from Feed, Live Preview and Share to Flickr, but however we are told that upcoming versions are intended to bridge any differences.
