The simplest way to transfer photos from an iPhone to PC selectively (not sync-all)
Windows 7 should see your connected iPhone as a Photo Camera. Just use the same software that you'd use for importing individual photos from a regular USB-connected camera. Also make sure to have your phone "trust" your computer by turning on the phone and selecting "trust" from the pop-up.



On OS X, you can use the built-in Image Capture utility (or iPhoto or Aperture if you have those).
