well.. i jailbreaked my ipod touch 1g a while ago and now i have 50 or so apps on it.. now its becoming sluggish and startup time is well over 2 1/2 mins or so.. i have a 16gb and i used up 9gbs and theres 4-5gb left.. my question is do i reset it into dfu mode or reset it through itunes????? and most importantly.. will it become faster (like when you turn it on for first time.. start up 10 secs..) cause i noticed this when i played asassins creed and my friend on the 2g got higher fps then me.. you could see my frames move literally..

thanks
