Plug in Iphone without Itunes?

Seemingly mi sis iphone isn't connecting to itunes. How do i do it? She needs to recover it urgently! Been trying redSn0w but isn't working =( suggestions please? Wud increase your level!

If you mean by recover restore just open iTunes plug in your iPhone and long press the home button and the power button together until iTunes logo with a USB cable shows up and then iTunes will give you the options to restore or update you can download the iOS with here I choose this link usually because I pause and continue downloading not like iTunes because if the Internet disconnected baaaaaaam you must retry
