I downgraded my phone to 1.1.1, activation and jailbreak.com worked fine.
Installed OktoProp and updated to 1.1.2 with iTunes.
After that i did the 1.1.2 jailbreak with SSH.
It said that the jailbreak was successful but after reboot nothing changed and after a few minutes nothing happened.
So I downgraded to 1.1.1 again and tried to jailbreak it but it didn't work!
What to do no???
