My iPod touch is working just great with few problems... I finally got push email to work with it, but I've run into a problem. When I lock the iPod touch, I lose my connection to the network. When I unlock the iPod, my connection is restored. Also, if it's plugged in and charging, it remains connected to the network. Is this normal? Is the iPod touch supposed to drop its connection when it's locked and unplugged?
