The iPad doesn’t come with a camera (unfortunately) but someone has figured out how to use your iPhone 3Gs as camera for your iPad via 2 camera apps and bluetooth connection. This might be a great method for those of you who carry both an iPhone 3Gs and an iPad to enable camera. Of course, I think this is only for taking photos/videos but still a solution.
All you need to do is download the Camera A and Camera B apps onto your iPad and iPhone respectively—note that Camera A will set you back a buck while Camera B is free. Once you’ve got the apps on your devices, make sure bluetooth is switched on, and open the apps. Ta da! You’ll see everything your iPhone’s lens sees on your iPad.
