We showed you the Camera A/Camera B iPad apps that allow yout o use your iPhone as wireless, digital camera. However, HDcam seems to be much more polished and is updated and ready to go for iOS 4 and iPhone 4 users.

The picture quality is pretty great, especially with the iPhone 4, and couldn’t be much easier with an automatic connection made between your iPhone of choice and iPad. Currently the app is only available for iPhone 3GS and iPhone 4 running iOS 4, so 3G owners are, unfortunately, out of luck.

If you tried the app before, you can expect some major enhancements in the latest update including the following improvements:

– 40% faster streaming

– HD images quality improved 30%

– Low-res images quality improved 300%

– Embedded photo gallery

– Fully automatic connection

– Minor bug fixes

You can pick up HDcam for iPad from iTunes now for $1.99.
