Hi all, I postet this in the iOS6 Bug post where someone suggested to open a new topic for this because I could reach maybe the one who knows a solution. So here is the message: Hi I got a huge bug.. I downloaded the beta 4 from the website and did a restore with the new ipsw. When its installed and wants to setup I enter my Pin code. It says success and connects to 3G Network. No provider is shown next to the bars. Normally Telekom.de was shown. Now if I try to activate the phone via Mobile Network or Wifi it tells me that the sim card is not useable with the device and I need to contact my provider to get a new one. I tried many different cards in my company but with no success. I can´t activate it..! I couldn´t even manage to downgrade using the redsnow tool. What I tried so far: Tried to restore with redSnow to 5.1.1. Tried to restore to 5.1.1 utilizing DFU mode. Tried to restore to 5.1.1 utilizing Restore mode. all with no success. I also opened a ticket at https://bugreport.apple.com Does anyone have another suggestion for me? Thank you very much!
