I do not know. I’m sorry. I’m not an expert on iOS devices.
Please note that WinSCP is generic file transfer client. It is not special tool for hacking iOS devices. Some people just find it useful for the task.
You can learn here how to connect to iPhone, iPod Touch or iPad with WinSCP though.
For other tasks, please refer to some of the iPhone or iPod Touch related site, like Forum on ModMy.com.
