Hey all,
I have recently finished theming and jail breaking my iPhone 4s with the sole purpose of making it an awesome astronomy tool. Here are a couple of screen shots:

It's quite customizable and I have already found it quite useful.
It's not just a themed iphone once it links with (apparently) "NASA's online Solar clock" and according to that, will turn a light shade of red and will become darker as the night goes on. I have quick re-screen enable for easy to use, I have multiple very useful astronomy and star gazing apps. Easy to see weather (Cloudy, raining, sunny, Clear moon, etc), real time and using one of the apps where planets, clusters, nebular, etc are currently in their orbit.
If anyone is interested I might be able to write up a small how-to guide with what I used to do it etc when I get some time.
Let me know what you guys think.
