I searched but couldn't find a clear enough answer... I intend to use http://www.hacktheiphone.com/111/iphone_step_1.html to unlock my iphone for T-Mobile tomorrow. I believe I have a 1.1.1 phone (based on my serial no.) I have been seeing the term SSH on this forum alot. Can someone explain why I need this? What is it for? Is the installation of it from AppSnap all I need to do? What if I don't do it? Thanks guys!
