So I found out that iTunes 7.7 was available so I updated my software. I also found out that you can download iphone 2.0 software on the internet so my iphone was still jailbroken so I decided to restore it before I attempted to download the 2.0 software. After I restored it itunes synced all of my songs and such back to my iphone and it wasnt jailbroken any longer. Then I tried to update my phone to the 2.0 software I had just downloaded from the internet and when my phone was restoring and updating it just stopped. So I put the phone into recovery mode and plugged it back into my computer and now it says it cannot restore because of unknown error 20. Now im screwed because its stuck in recovery mode and i cant do anything with it. Any help please?
