I am guessing that you can transfet larger videos by reversing the alternative method of transferring via Windows Explorer. When connecting the iphone to the computer without itunes running, the computer recognzes the iphone as a storage device. This what I found on a similar blog --- "With your iphone connected to your computer just go to My Computer and find your iphone. Right click on your iphone and it will give you an option to get pictures. When I clicked on this a scanner and camera wizard came up and guided me through the process. Just select the pics you want and the folder where you want them to go to on your pc. All of the pics that I transferred appear to be in the resolution that they were on the phone without being compressed or reduced." This is what I am going to do. Remember syncing with itunes is not the answer.

hope this helps.
