1. download openSSH free from cydia
2. download terminal free from cydia
3. after both are installed restart your device
4. open terminal and type "su root" with out the "'s
5. then type the default password which is "alpine"
6. now type passwd and type a new random password twice. (one you will remember)
7. download a ftp application. depending on if your on mac or windows, get winSCP for windows and filezilla for mac.. two suggestions for free apps unless you already have your own you use..
8. you must be connected to a wifi connection for this to work so and we need your ip address, so now on your iphone go into the settings tap wifi then on the blue arrow on the connection you are connected to.
9. take the ip address and use it as the connect ip address and use port 22 or 25 i think it is.
10. connect and accept the certificate.
now you will see the directories on your iphone so you can move any file you want any where..
