I've had my iPhone 3G with cydia for about 9 months and my iOS is still 3.1.3. Everytime I try to install iOS 4.0.2 (most current jailbroken?) my iTunes says error 3194 which says to fix it I need to update itunes to current. I did that and it is not working. Also I just updated cydia and now it will not open on my Iphone. WTF do I do to make this work and up to date BESIDES buy a iPhone4?
