I purchased it right after they released it before kickoff weekend. Although I've not had a lot of time to devote to playing it yet I have fooled around with it some and was pleasantly surprised at what they were able to pack into the iPhone version. I'm looking forward to taking the time to actually play a few matches and tweak the settings and get more familiar with it.
It's a busy time of the year though for sports though. My baseball team is still in the hunt for a pennant and post season play and of course NCAA & NFL is in session again.
I have also played it. The graphics and control is awesome. Playing football can be so much funny in iphone I never thought. Easy to play primary level but next it gets harder and more enjoyable.
