One of my all-time favorite iPhone apps is Instagram. It is what flickr should have done for its mobile client. It’s finally out for certain/some Android phones and can be downloaded through Google play. Check the requirements before you download and make sure your phone and the version of Android you are running are compatible with this release.
I’m not one of the snooty iOS people who is dreading the new influx of users. I’m stoked to see what kinds of things will be shared and made. This is great for everybody. I apologize in advance if any Android users on Instagram get grief from iPhone people.
If you are still on the fence, here’s a comparison on TNW of iOS & Android versions of the app.
