DropCopy makes iPhone file sharing easily. Like its desktop cousin, the mobile version of DropCopy has the easiest way to send files simply between any combination of the iPhone, iPod Touches and Macintosh computers on your local wireless network and worldwide via the Internet.
DropCopy is so cool. You can transfer your files from one iPhone to another iPhone without a computer involved. The devices can simply "see each other" when they are on the same wifi network.
DropCopy mobile also includes a quick view to see the function of many types of document and multimedia, including MP3, MOV, PDF and DOC, right on your iPhone!
You can also access your iTunes library on the iPhone with DropCopy.
Note: with the version 1.0 will be allowed to "approve transfers" for the moment. In seeking to make the safe transfer, we have become too safe and rejects dropcopy mistakendly transfers which are not expressly "approved". This has already been set and will come as a free update within a week!
