Can't get my iPhone 3GS to get past the DFU part..
I plug my iPhone in, open the Greenpois0n app, click the JailBreak button, it starts the countdown, prepare to press and hold sleep, etc.. I go through the whole process following the steps exactly, and at the end it says Try Again? iPhone screen is black(off) but can still just barely see the lockscreen on the screen.
Anyone know how to get past this?
