    so i have the latest tinyumbrella and i have it plugged in, then i start tss but what after that? i have a mac and will be using hte limera1n to jb. i just dont want to mess anything up. i also want to preserve my baseband for future selling of my iphone4.

    how do i just upgrade from 4.0.1 to 4.1? i know you have to do option/restore in itunes, but dont know where to go from there. please help quickly.


    also is itunes 10.0 ok or do i need to upgrade to itunes 10.0.1???

    Its hard to go wrong with the upgrade using Tiny umbrella but you should look at the readme on the site. The basis on with TU umbrella works is that apple is signing both the FW and the BB separately. Tiny umbrella spoofs the FW signing but not the BB signing and hence the second part of the upgrade fails because the BB is not signed. This gives you a 1004 error and you have to kick it out of recovery. You can do the same thing by changing the host files and using Saurik get same error and then use TU to kick out of recovery.

    Yup. IIRC Tiny Umbrellas website links to a factory copy of 4.1

    go to iclarified and download the proper version of the firmware for your iphone
    start up umbrella
    start up tss server
    go to itunes, and option+restore
    pick the firmware
    wait for it to install
    if an error message (1004?) comes up, exit itunes + umbrella and disconnect the phone
    connect the phone, and load up umbrella
    click kick out of dfu mode
    you're done and probably kept your original baseband

    load limera1n
    click make it rain
    follow instructions

    done

    to install cydia press on limera1n icon
    install cydia
    click limera1n icon again, and click delete limera1n

    Download the firmware for your device to your computer from here:

    http://ios.e-lite.org/

    For example, if you have an iPhone 4 and an SHSH for iOS 4.1, click on the text "historical (click to expand)" at the bottom of the page and download the iPhone 4 "4.1 (8B117)" firmware.

    If you run TU, you can save your SHSH for whatever the current version is even if you're not currently running it.

    You are completely wrong :p once your blobs are saved, you can downgrade back to the version saved.

    And, with a 4.1 SHSH blob saved and Tiny Umbrella, you can upgrade to iOS 4.1 without upgrading the baseband.

    All things being equal you should set up as a new phone to prevent issues.
