So here's the scenerio:

I just got my iPhone yesterday and was just looking at it, and tried to put it into restore mode (big mistake) without having it plugged into the dock.

So I followed the steps and installed iTunes 7.3.2 and plugged it into the dock, I did the restore method again by holding down PWR + Home buttons for 10 secs, and windows detects it. (Great)

Now with iTunes open and after I try and restore I get this error "the iPhone 'iPhone' could not be restored. an unknown error occurred(-8).

what can I do to fix this? My phone won't even turn on now and its just a black screen

Try opening itunes, plug in your iphone, and holding both power and home buttons down for a long time...this usually works.
if not, download itunes 7.4.1.2 here : http://appldnld.apple.com.edgesuite....TunesSetup.exe

uninstall your old itunes, reinstall the one from the link above, then try and connect agian.

hold the power and home button for at least 25 seconds the iphone will restsrt 2-3 times before entering restore mode.

Ok I was able to get the restore logo back on, but am still receiving an error. Do I have to upgraded to 7.4.1.2 cuz everywhere I'm reading is telling me to use version 7.3.2. Does it make a difference

Ok, My fault I wasn't hitting shift when I clicked restore. But after doing some more reading I found out it can't be on the revovery screen however, but rather the blank screen.

New Problem. When I try and put it into restore mode, after windows detects it I get the error: The iphone "iPhone" could not be restored. An unknown error occurred(-14)

I've tried searching the forums but can't find that error code...
