So, this morning, I unlocked from 1.1.1 to 1.1.2 using anysim. Everything went well. Then, when I tried to install some 3rd part apps using installer, it has this error, saying full disk space. So, I follow this guide ( http://www.iphonestalk.com/how-to-fi...y-iphone-apps/ ), and typed a few commands using terminal. After I restarted the iPhone, all the icons disappeared. Since I have no idea on what to do, I am really a newbie. I went and restore the iPhone to 1.1.2 otb firmware. Right now, I cannot do anything, all I have is an emergency screen(cannot access to springboard) and iTunes will not recognize my iPhone, saying that it must have a valid simcard inorder to activate So, I was wondering...is it possible to unlock my iPhone again? If my iPhone has a serial number (4th and 5th digit lower than 45), will this even help at all? Or are there any solutions? I felt so stupid, unlocked, then relocked it again.. =(. Thanks, any opinions are welcome, thanks!
