There is an easy way to copy a video recorded with your iPhone 3G S to your computer.
If you’re on a PC, go to My Computer and look for “Scanners and Camera”. You should see your iPhone there. Double-click on it and and save your photos and videos to the desired location.
If you’re on a Mac, open the Image Capture app. It will recognize both pictures and videos recorded with your iPhone. Drag and drop the video where you want to save it and that’s it.
