IPhone File Server & Client to Create Proxy Alternative to Personal Hotspot Tethering
I have found a few apps in the App Store that claim to be both an FTP client and server. That means you can run a server on an iPhone, connect to it from a Mac, transfer files to my phone, and then to a remote server (or vice versa). This would greatly simplify the process.

The apps are:


FTP On The Go Pro
Easy FTP Pro
FilesConnect
FTPManager
iStorage 2


I believe there are others but these clearly explained that they include a server and client.
