Ill assume that you have openssh already pre-installed on your iphone/ipod touch. If you havent done it already, jailbreak your iphone/jailbreak your ipod touch and install cydia on it. By using Cydia, install openssh on your iphone/ipod touch.

If you have no idea what im talking about, google “jailbreak ipod touch” or “jailbreak iphone”

After that you can access your iphone/ipod touch file system either through wireless net or through USB.

Connect via WI-FI

To connect, on Session tab of WinSCP Login dialog specify:

* IP address of your iPhone/iPod Touch into Host name (You will find the IP address, if you go to yours iPhone/iPod Touch menu Settings > Wi-Fi and choose the network you are using);
* root into User name;
* alpine or dottie (depends on firmware version) into Password;
* You may need to set longer Server response timeout on Connection tab;
* Keep default SFTP File protocol;
* Click Login.

Connect via USB

* Install iPhone Tunnel Suite on your computer (it ships with WinSCP, so you do not need to install it separately);
* Connect iPhone/iPod to your computer via USB;
* Run iPhone Tunnel Suite;
* Click iPhone Tunnel in iPhone Tunnel Suite menu;
* Launcher starts, keep it running;
* Click WinSCP in iPhone Tunnel Suite menu;
* On Stored Session tab of WinSCP Login dialog select pre-configured “iPhone” session;
* Click Login.
