I tried jailbreaking my iPhone4 on both a Mac and a PC and got the same problem; the screen shows a large amount of white on black text and then the words "please wait..." fill the screen, row after row. I waited a long time and nothing changed. I then tried upgrading to 4.3.2 and can't even do that, since error 3194 comes up. Could it have something to do with the Gevey SIM overlay I have installed? I thought it wouldn't make a difference, since the phone is technically off when this is all going on. I'd really like to install some stuff onto my phone but can't do more than basic functions right now. Please help!
