Allright this can get pretty interesting for iPhone 3GS users who have iPad too who wished of a cam feature on their iPad. For this to work, users need to download Camera A app from iTunes store onto their iPad and Camera B app to their iPhone 3GS.
Through Bluetooth both the devices should be connected and respective apps should be initiated. Camera A app would be able to display images on iPad from iPhone’s cam. In order to capture a picture, users should tap the camera icon on the app screen. The image would be transmitted from your iPhone to iPad. Users may also save the image on their iPhone too by turning on the option of “Save To iPhone Library”.
