I've got the chance to beta test a new game on my iPhone, which is awesome, but they want my IMEI number, and I am a bit clueless about how to find it. Help!?

Another game for the iPhone? I already have over a hundred games on my iPhone (one reason my kids are always stealing my phone!) so when my friend Gary dropped me a note to let me know that his long-time hit Gold Strike [iTunes link] was now available through the iPhone App Store, I was skeptical. He writes great games but still, another game? Fortunately, I sprang for the $0.99, dropped it onto my phone and am impressed!

I've heard I can use my Apple iPhone 3GS as a Kindle without actually buying a Kindle from Amazon. How is this possible and how do I do it?

I watched the latest Apple announcements and was pretty impressed by the different things that Steve Jobs talked about, but the one that caught my attention was the iPhone Application Genius recommendation service. I'm a bit of an app-aholic, so I like to see what's new, but with tens of thousands in the iTunes app store, well, a recommendation service seems like a great idea. How do I use it?

I've been hearing a lot of buzz about the new Skype for the iPhone 3G, but am a bit lost about how to download specific applications onto my phone. Can you show me all the steps?
