In December I bought a jailbroken iPhone 4 on Ebay to replace my iPhone 4 that disappeared going through security at the airport here in Germany where I live. While I was back in the US I received the iPhone. While in the US it worked for games and what not, but since I did not have a SIM card it could not make calls or do anything when not receiving a WiFi signal. When I returned to Germany I got a new SIM card from O2, using my previous plan. All worked great for about 3 weeks. Then last Thursday I got a prompt to update the Operating System. I am not tech savy, so unfortunately I agreed and that was the start to my problems. Lesson learned for sure. So I was able to reset my phone and I am now on the activation part. The problem is that I do not have the original SIM card or a SIM card from the US. I am not sure what carrier the phone was with originally as I bought it on Ebay. I have read that using LimeRa1n works, but I did that yesterday and at the end the message said "to enjoy my jailbroken phone", but my phone still says that I need to activate it using the original SIM, if I take my German SIM card out it says Activation Error. Is there anyway that I can activate the phone with out a SIM so that I can then jailbreak the phone so I can use it here in Germany again?
