Thank you! However, the slogan isn't necessary to put (as it will generally be very small to fit in a fraction of the iPhone). Also, the logo should be more 1 dimensional and simple. Finally, the full name should not be included as it will be hard to read on such a small square on the iPhone. If you've seen any other apps on the iPhone market it should be structured to look like those. Thank you for your entry so far though!
I also like the above part of the design with the arrows and circles. Maybe you could shape the circles to look more like faces and put a city look a-like design in the middle of the arrows and make the arrows skinnier? Also making it look more two dimensional would be great!!! This should look simple though so if it gets overboard complex its probably not the best for the iPhone. Thank you!!
