I've downloaded this app for my iPhone4 as i work crazy shifts and have random days off. My GF has a new iPod touch and has also downloaded the app but she doesn't have the option 'Device Calendar Sync' so she can sync her iPod touch with her iCal/Calendar on her iPod - the button just isn't there. Does anyone use this app and/or know if this is simply an unsupported feature on iPods?
