Geof posted yesterday that Instagram might not make a native app for BlackBerry 10, but possibly an Android ported app. However we just got word that an app named Instago will be available to fill that Instagram void, should be available mid-March. See the video of Instago in action below:
Posting photos from this app will not be possible, Instagram would need to come in and make an exception or publish their native BlackBerry 10 app or even an Android ported one.
