Instagram is free and there's no reason to pay 2.49 for a crappy 3rd party app.
yeah its free but 2.49 beats not being able to post anything(if you care for this social network).
and its not a crap app. in fact we should give credit to the developers for thinking outside of the box and finding a solution like this. I didn't see anyone else doing something similar. Not on Symbian not on BB and not even on android (until they got the official app).
