So twice in the last month I have woke my iPod Touch from sleep. After waking, I try to access my e-mail and get an error that 'the server can not be found'. I have had to do a hard reset, i.e. holding the home and power buttons until the screen goes blank. When turning on iPod I get a screen showing the charging cable and the iTunes icon. Does anyone know what is going on? Your help is greatly appericated.
