    Today I stumbled on upon this guide by a commenter Rainz on the iPhone Dev-Team blog on how to get your iPhone 4 to 4.2.1 while keeping the baseband 1.59.00. I don't know if this has been posted so yet (didn't look :eek:)

    There is also one for windows by another commenter 49ershaha

    In the screen shot below is my iPhone 4 which I just upgraded.

    winterny did post instructions in reply to a post, although that was mac-centric. Considering how many people are wanting an untethered jb and want to preserve their 1.59 bb, repetition probably isn't a bad thing.

    Yes, I came across that a few times on other peoples reply's to threads but hasnt had its own thread yet I believe.
    So pretty much you gotta use TU and upgrade to 4.2.1 instead of restore.
    Then you will be able to kick device out of recovery with TinyUmbrella.
    Good info.

    Yes sir. The key is to have the host files edited. If you don't the baseband will upgrade.

    Correct.
    Either hosts edited or TU TSS server running while you update.

    could this sort my no service and update 4.2.1 keeping my 1.59.00

    Hi would this be a solution, got a no service issue on iphone 4, 4.0 & 1.59.00 done all uninstalled xellize and ultrasnow. All new to me, I have TU but not sure how or where i get ipsw files on to TU is it the same as iclarified. Baby step description as I am new to this still. Very little to lose if it does not work as i can not get it out of no service any how. many thanks teadigger

    So even though Rainz said not to do it, could you still preserve BB by running TSS server while updating instead of editing host files?

    Its the same thing. You can do either one.
    All it does is it blocks the communication between your iphone and Apples servers so the baseband isnt updated but everything else is.
    You can accomplish that by running TSS server thru TU or editing your hosts to point to cydias server.
