well, well, well... today something was happened to itouch. I updated it unofficially from apple server. tonight I just played super monkey ball, then finished, clikc home button. it suddenly turned to recovery mode. so I hooked up with itunes, clicked restore. surprisingly itunes just download 2.0 firmware without any demand to pay. firmware was the same with itunes support. (5A347). I still have no idea why game caused mine as recovery mode. do you guys know why?
