So I've had the ipad2 a week now. Setup fine on my wi-fi network. I'm loving it. Setup Mobile Me last Saturday, to locate the device. Apple ID and password working fine. Going to travel soon, so checked the map and it does not show up with a message "Location Not Found". It does give me a message box with the iPads correct name and options to Lock Wipe or Play a Sound. But why doesnt it locate it on the map? Open to suggestions on how to correct this.
