Besides Winterboard which is an obvious one, get Appulous, or was it called Instalous? I can't remember, haven't used my iPod in a while. But it lets you sync 3rd party apps to your iPod. I used to develop iTouch apps in Flash CS5 with a cracked certificate and run them on a jailbroken iTouch. It wasn't the most professional thing, but it was fun.
