TinyUmbrella now supports saving SHSH iOS 7 and 7.0.1 for all devices. Apple only allows you to restore to the firmwares they ‘sign’. This ‘signing’ only lasts for a limited time. Once they stop ‘signing’ the SHSHs for a firmware, there is no way to restore that firmware ever again. TinyUmbrella requests SHSH signatures for firmware restores and plays back those signatures enabling iTunes to continue the restore.
Updated TU to support iOS 7 and 7.0.1 – iPhone 5s , 5c
