This is sooooo sweet.   Just came across it today.  The program is called Discover. What it does is give you limited access to your iphone like a USB drive except this does it using WIFI!  There are two other programs I have already that give you wifi access but whta discover does differnetly is it give me access the photos! I also have the ability to set login and passwords as well as public and private folders.  Since its wifi, sharing iphone to iphone is very easy.  it even has a browse button to look for other iphones!

Even better?  This app is Free!  So go get it.
