iPod touch problem - Every time I install a new app on my iPod touch, nothing happens. Then I open it up, try it out, and quit it. After that, it freezes. I try restarting it but that damn apple logo comes up and stays there for about ten minutes (I didn't bother waiting any longer). I connected it to my computer and put it into recovery mode. Then this f**king error comes up: "An iPod has been detected, but it could not be identified properly. Please disconnect and reconnect the iPod, then try again. An unknown error occurred (1619)." Does anyone know how to fix this problem?? P.S. by the way, I DID try disconnecting and reconnecting it a LOT of times.
