hi , there , i recently tried searching forum and could n't find answer.
i recently tried a chinese software called 91shouji( 91手机） kind of itunes, and lets transfer songs and install apps, but i messed it somehow and then it asked me to sync with itunes, which if i do , again asks me that i need to update to new os which i dont want . i just temporarily deleted a small file , which stablized my ipod in iphone4 . but form then i am having this strange problem like skipping songs, tracks with uneven volume and also half songs , i checked my computer, its okey .

so i want to know is there any way i can just re-install ipod in iphone4 ?
would be great help .
