Sparrow iPhone icon

Dear Dribbblers,

We are working hard on Sparrow iPhone and it should be available soon.

We are still not satisfied with the various icon iterations we made. It's hard for us after several months to take a step back and know what works best.

In the attached image, you'll find 9 different versions of the Sparrow icon.
We would like to know which one you'd like the most and gather some advice.

Thanks a lot
