Accessing iPod Touch with C++

I've been searching nonstop today on methods to access the iPod Touch's root with C++ via USB.

Like QuickPwn and many other managers.

I tried debugging all those apps to find out how they get into the ipod,without any success.

i know that getting inside an Ipod Nano,etc is fairly easy since windows assigns a drive letter to them when plugged in.

But the iPhone/iPod Touch 1/2 don't have that feature.
i have searched all registry,command prompt,but no luck at all.

So,Do you guys any idea or have managed to get inside it?

Help will be greatly appreciated.
