onnect iPhone with winSCP via USB

I have always been using PPC, so I am totally newbie to iPhone. The iphone user interface is really amazing. Anyhow; my ex's iPhone got bricked by her cousin. So I decided to take the challenge instead of paying over $150 to unbrick and update. Unfortunately, I stuck at the first step already...to connect the iphone via USB cable (not wifi, since that feature was disable by the bricking) with WinSCP. I could not get the IP address from the iPhone because I can't get it to connected via Wifi. I have tried random IP address online with login: root and password: dottie or alpine but unsucessful. I either got message like connection timed out or host not exist. I hope to get some help from you guys/gals to get me started the unbricking process. greatly appreciated.
