I have an OTB 1.1.2 which was happily jailbroke and working. I've been through the wringer trying to get up to 1.1.3 jailbroke, and no matter what I do, I cannot get the phone function to work. I have an AT&T account, but not an iPhone data plan - so I can't use the activation wizard in itunes.

I keep reading about baseband 4.6 is different, and how the file lockdownd should fix the issue, but I can't find a solution to my problem.

So, how do I get the phone function working again?

Thanks!
