when ever I put my itouch into sleep mode the sleep mode sound laggs. About 5 mins after the ipod enters sleep mode the sleep mode sound goes off. I'm on FW 2.2(5C0) and I have restored my ipod around 7 times cuz of this problem. I'm going back to school soon and I dont want the sound going off after I use it durring class. And yes I have tried turning the sound on and off and no I dont want to turn it off cuz it comes in handy when I use the mail.app.
