So here's the deal. I recently got an iPod Touch, and while I'm happy with it, it's a little...plain. I've been told that to spice it up, I need to jailbreak it. All I really need is a theme, wallpapers, backgrounds, etc. The usual. Maybe put some emulators on it if I can figure out how to do that. But I've read through these stickies, and they're all Greek to me. So if someone could be really awesome and explain this step by step in layman's terms, I'd be really grateful. Also: If I Jailbreak it, can I still upload music, videos, apps, etc to it? And if iTunes updates and forces an iPod update, will it break it or something?
