Hello, I succesfully managed to jailbreak my 3GS with iOS4 using Pwnagetool 4. The only problem i have is that Cydia won't launch. It's crashes before i see anything. I really need Cydia.. I managed to unlock my iPhone anyway by using a technique i found on some chinese website (placing the two .deb files in a specific folder). I can't use SSH or anything because Cydia won't start up! Re-jailbreaking is not an option. I read somewhere that there's a fix for when Cydia crashed after a jailbreak, but that accounts for the fact that there are other (old) files in a specific folder on the iPhone. Problem is; there are no files. So it's a completely new set-up, completely new Cydia that won't launch. Is there a way to install Cydia from my Mac onto my iPhone. Is Cydia not compatible with iOS4 or what?
