Kristen, for the Pocket Closet you take pictures of all the items in your closet and then you can shuffle through them. The design is the same as the coverflow design in iTunes, where you can browse album covers...except it's your clothes instead of music.
I can't seem to find the Top Shopping app on iTunes, but I can find it on my iPhone under the "lifestyle" category. Honestly it wasn't as great as I thought. It just gives you deals that it happens to have, rather than letting you search for deals. So if I wanted a shopbop coupon, for example, and they did not have one on file, too bad for me. I'll keep an eye out for a better one.
Nicole, I do not think of my iPhone as a fashion accessory at all. It needs a case so I'll probably get a nice one for it, but I am getting it mainly as a functional item to prevent it from being scratched and damaged. I'm a firm believer that if it's necessary, it may as well look good.
I'm leaning towards this one:

I really hate any kind of case that adds a lot of unnecessary bulk, and I also don't like most "fashion" cases with crazy prints and loud statements. I think the design of most Apple products is beautiful, sleek, and simple, and most cases unfortunately seem to detract from that.
