Today, I got my iPod Touch replaced by the apple store, and it came with firmware 1.1.3. So I downgraded to 1.1.1 like I always did, and then when I went to jailbreakme.com, not matter how many times I clicked install appsnapp, nothing happened. It usually crashes and says installing tiff......but no dice. I'm on 1.1.1 for sure, and I never had this problem with my old iPod.
