Hello, I got an iPhone 3GS locked to AT&T, iOS 4.2.1. I installed the iPad baseband and jailbroken my iPhone with the latest Redsn0w ( 0.9.9b3 ) . Wireless is ON. and Cydia is just a weird gray icon when trying to open Cydia it just takes me back to Home. Now I also noticed it happens when I open Safari. Also, It's not the first time I'm restoring the iPhone and trying to fix it. I tried like 3 times and it keeps doing that. How can I fix it? Thank you very much!
