    I didn't see one that was stickied, maybe this one should be.

    Could someone explain what the safest way is to upgrade to 4.1 with a jailbroken iPhone 4.

    Please be detailed.

    Download Tiny Umbrella 4.1.4
    Plug your iphone in.
    TU will recognize your ECID
    Click Advance Tab
    Device / Version : Select Iphone 4, 4.1 shsh blogs
    Click Save shsh
    Wait for answer
    Now start TSS Server
    It should say now connecting.
    Do the Shift + Restore to 4.1 ipsw
    Your iphone will be restored to 4.1 but baseband preserved at 4.0

    The catch here is your 4.1 shsh blogs must be stored in Tiny Umbrella.

    When you do a shift key on your keyboard + restore on your Itunes, a box will open up and you choose your firmware.
