I'd say downgrade and jailbreak 1.1.1, just to see if you like it. If there's nothing amazing about the jailbreak, maybe just go on the straight and narrow. There's really no reason to jailbreak if there are no apps that are amazing to you (unless, of course, you're into piracy...). But 1.1.1 is where to start, and the jailbreak is almost entirely painless.
Good luck!
