i have been having this problem for a long time and have restored many times but it is still slow. its laggy in apps like TTR and even simple ones like fireworks. its epically slow in like star wars in stuff. it takes a long time for apps to load and even when i reboot everything is still slow i have the ipod touch 1st gen on 2.1 jb'ed and the only reason i updated from 1.1.4 is because i heard that 2.1 is a lot faster. and it was a little but compared to my bros ipod it is a lot slower.
