So i had a 2.1 3g iphone and jail broke it all was well, i updated from itunes to the new firmware 2.2.1 Which un jailbroke it but still had a couple apps and things left so i'm not sure if it restored it or not. I use this guide on here to try and jailbreak the new firmware but it once all said and done i do not have installer or cydia on my spring board. really frustrating and i've done it a couple times i did it with the new logo and it shows up but still no cydia or installer any ideas?!? thanks for any help.
