Hello, I have a clean unjailbroken iPhone 4, ver. 4.0.2, baseband 01.59.00.
It is December 11 2011 today. I was wondering if I can selectively upgrade to 4.2.1 only using tinyumbrella+greenpois0n while preserving bb?
I've read somewhere that says once Apple stopped signing 4.0.2, I can't upgrade to that firmware and my only option is upgrading to the latest one. Can you confirm that for me? Thanks!
