Now that I have an iPhone, I am finding that the application icons are a complete jumble. I like things neat. Is there a way in iOS 5 to move them around so I have my favorites on the first screen, and so on?

I still use Hotmail because it's what I am familiar with and it's what I've been using for years, but I'm starting to get jealous of my friends on Gmail because of all the cool themes they can apply to their mailbox to make it look cool. Is there any way to skin or otherwise tweak Hotmail to make it look a bit more cool?

I was just looking over at someone else's computer and noticed that they had a completely different look and feel for their Google Gmail Web pages. I mean, REALLY different look, with ninjas and everything. She said she'd tweaked her "theme" but I don't know about that plug-in. But, damn, it looked cool. How can I tweak the appearance of Gmail?
