This is my very first posting here. First of all I have to tell you how glad I'm that you do such a amazing job. Thanks everybody! Keep it up!
I jailbreaked my 1.1.2 otb iphone by downgrading to 1.1.1. After the jailbreak I installed TurboSIM and had no troubles with 1.1.2.
I decided to upgrade to 1.1.3 by iClarified installer method (http://iclarified.com/entry/index.php?enid=611). It run until the end and froze my phone for hours. Then I rebooted it. Afterwards it end up in maintaining mode. (cable with itunes icon). Next I tryed to restore back to 1.1.1 by itunes (option + click). This runs until the usual error code 1015. But jumps back to maintaining mode afterwards again. When I try to "boot from recovery" with jailbreak.jar nothing happens. It doesn't reboot.
I tryed to restore every version now without sucess. I also tryed to repair and upgrade to 1.1.3 by itunes. But also here I end up in the maintain mode.
Any idea? Would be great if you could help me.
