Since i upgraded to 3.0 i've been expierencing a lot of problems with my ipod...it freezes, lags, etc a lot. when I jailbroke it it made things worse.

Then i upgraded to 4.0 and still the same. If someone sends me a lot of msgs in ebuddy it freezes and lags, if i am browsing a website the music i listen to starts to skip and eventually stops. i have to forcfully shut it down about 3 times a day. is there some sort of software error with 3.0+ ?

And it still does it even if its not jailbroken so i dont think jailbreaking it is causing it

thanks!
