Android Hipsters rejoice: Instagram is here!
After previous teasers, Instagram has now made their popular iOS app available for the Android platform - you can install it on your compatible Android device through the Google Play Android Market. Please note not every Android device is compatible. You will know whether you device is compatible or not by whether the Google Play Android Market allows you to install it. With this being the initial release, do not be surprised by some early kerfuffles.
A primer on Instagram is available at the Instagram blog.
