Im following the tutorial on how to jailbreak and upgrade an OTB 1.1.2 iPhone to 1.1.3. I now have a jailbroken iPhone 1.1.3 with Installer but no phone service.

Apparently for the last step I have to upload a file called lockdownd but I cant access my iPhone. I am using Transmit FTP. Username is root and password is alpine. I am using SFTP mode which worked before. Now every time I try to connect it says "connection refused".

Can you tell me whats going on and how to fix it or if there is another way I can activate my iPhone to have service again?. I am on AT&T so I dont need to unlock it for another carrier.
