    Too late now, I think.

    Tried to do a custom restore of 4.2.1 last night and I got the “this device is not eligible for the requested build” message. Tried to save my SHSH blobs using tinyumbrella and it only saved those for 4.3 (new iPhone 4.) Grrr…

    Normally I just save blobs without unchecking box and they also get saved to Cydia
