title: iphone sdk - why is the video returned not full res?
body: <p>im developing an app for the iphone and im able to get a video using a UIImagePickerController
  the problem is that the video thats returned by the UIImagePickerControllerMediaURL is not full resoultion -- its only 480 x 360 as opposed to 640 x 480 like the videos that sync to my itunes.</p>
  
  <p>-please someone tell me this is not a limitation of the current sdk?
  - how can i work around it and is there a way to set the uiimage picker so its taking full res video?</p>
