I tried to reset my iphone 3gs back to its original settings so that I can sell it. I went to setting - general - reset - erase all content and settings. Now my iphone shows an apple icon on a black background. I have read other threads that explain how to get into recovery mode and it isn't working. http://ipod.about.com/od/iphonetroubleshooting/a/Iphone-Recovery-Mode.htm My iphone was jailbroken using a program called redsnow. Does anyone know how I can fix this problem and restore my iphone? Thanks so much.
