Hello everybody, and thanks in advance. I need to test an application I'm developing in an iOS 4 (damn customers...), but I've only had iOS5 and iOS6 devices for some time. I've tried downgrading an iPad 1 from 5.1.1 to 4.3.3 and 4.3.5 to no avail, I've followed many tutorials using a combination of TinyUmbrella, Bluefreeze, iFaith and Redsn0w. I don't mind if it's tethered and I don't have any data or apps that need restoring, this device is only used for testing. I don't have any SHSH blobs. Any help?
