If you're like me, your USB cable is attached to your charger, plugged into an outlet buried under your bed. It's a real pain to pull it out just to upload a few songs to my phone. FTPServer lets you take advantage of your 54Mbps wireless network (that's nearly 20 times faster than Bluetooth) to upload files just as easy as drag and drop. All you need is an FTP client, like FileZilla for example. It's so much more convenient. Just launch the app, fire up your FTP client, and start uploading.
