Currently I am using iOS 5 Beta on my iPhone 4 GSM. But now I am not able to downgrade it to iOS 4 Beta. Last summer I enrolled in iDev program and signed up to be an iOS developer. And after that, in the earlier period of this summer I downloaded iOS 5 Beta. But, as now my developer account is expired from last few weeks and I am no longer a developer, I got to know that I am not able to downgrade my iPhone again to 4.3.3. And today a message appeared that was saying that one of the software on my iPhone "Gabe's iPhone" has been expired and it should be updated to a newer version. Now, I donít know how to overcome this issue. I am not able to use my iPhone as I am stuck at the activation screen only. If anyone has any idea about how to fix this then please reply with a solution.
