There could be quite a few ways to SSH into iPhone and access the iPhone file system (gain iPhone root access). If you’re on Mac, you might try CyberDuck while WinCSP is quite popular among Windows user. Both of those are used to sync wirelessly though, using Wi-Fi. My quest for an alternate started when I had to get iPhone root access over USB.
I found i-FunBox, the easiest tool I’ve ever used to get root access for iPhone. Process is real simple and is not as complex as it is with WinCSP.
How to Get iPhone Root Access (via USB)
Step 1: Download and extract i-FunBox
Step 2: Connect iPhone with PC via USB
Step 3: Run i-FunBox
Bang! i-FunBox will automatically detect your iPhone. You can now browse your iPhone file system. No connection configuration. It doesn’t get simple than that.
