First Windows Phone 7 App

So developed my first windows phone 7 app the other day when I attended a Microsoft phone camp, it was a student loan calculator, received some free gifts for my app winning the competition. Finally got my Microsoft t-shirt, a windows phone developer pack along with other bits and bobs. So the app went through the certified stages and failed on some minor errors, so going to have to unpack and fix these errors now before re-submitting again.
