Apple released an updated version for iOS 5.1.1 (9B208) for iPhone 4 GSM while the previous version was iOS5.1.1 (9B206). We are not confirmed about this release that Apple why updated this because no changelog is available, it’s likely a small bug fix given its slight build number difference. So stay away from this until given the all clear is sounded with regard to jailbreak compatibility. So, whatever you do, just hold off from updating until we, or the jailbreak dev teams give you the green light. Till then, you may sit back and forget that iOS 5.1.1 9B208 ever happened.
