Help please i have an iphone 4s (UK, locked to three network) with ios 5.1 itunes 10.6 running on windows 7 x32. i'm planning to update to 5.1.1 (or if possible downgrade to 5.0.1) so that i can jailbreak. however when i try to update using the downloaded iphone 4,1 5.1.1 restore.ipsw file using itunes, the process fails and advices me to update to ios6. i also tried using redsn0w, sn0wbreeze and tiny umbrella or even the editing hosts file. but all were of no use. i have downloaded both files and tried updating using above methods iPhone3,1_5.1.1_9B206_Restore.ipsw and iPhone4,1_5.1.1_9B206_Restore.ipsw I don`t want to update to ios 6 as of now.
