Is there an app (jailbroken or otherwise) that lets you transfer files between your computer and your ipod touch over wifi without having to install something on the computer? I am using filemagic and checked out a few others but they all seem to require you to install a separate application on the computer. In other words, is there something that integrates to the native windows file explorer, so that for example an ipod would show up as a usb drive connected to the computer. Wi-fi sync is similar but it works only for itunes syncing. I want something that transfers files directly. Thanks a lot.
