Yeah, it requires Android 4.0 or newer to run. It was a decision we made at the beginning since we don't own Android devices running those versions and didn't want to spend all of our time making the app compatible with all android versions (or at least starting at froyo).

Your phone version is in the lowest 12%-tile. No offense to you, but as an Android developer, I'm content making my minimum required version Ice Cream Sandwich if it means avoiding any complexities.
