My problem is, that after complete unlocking version 1.1.3 (jailbreak, activation, unlock) with ZiPhone it still says "no service". I think it was bought in August 2007. It's one the the first iPhones. I tried to downgrade to 1.1.1 and then it works until I have to install oktoprep. It's not in the install. I tried to add the link: "http://hackthatphone.com/1.xml" but afterwards I can't download it. So I'm stuck there. Any help? Even if it would work with installing first 1.1.1 and upgrading step by step to 1.1.3 I'm not sure if it will work.
