So I've found two sites that say you can, but can you really downgrade from 1.1.3?

    I'm curious about 1.1.3 and want to update my jailbroken 1.1.1 iPhone to it (Only really OFTEN use two applications on it, both of which I found web replacements for). Now, I'd like to be able to downgrade if I don't like it, and I've heard often that you can downgrade from 1.1.3, but it won't function as a phone anymore....Just an iPod and such. But according to these two websites (http://iphone.unlock.no/ and http://www.winandmac.com/mobile/iph...3-and-make-it-work-as-iphone-again/#more-1040) you can downgrade from 1.1.3...

    Specifically, in the first link is stated: "Downgrade the main firmware:

    Connect the phone to the computer and launch iTunes (v7.6 NOT recommended).
    Restore your phone like explained in details here.
    You will get an error when restore is complete, just ignore it and run AppTapInstaller.exe (to Mac users: iNdependence should do the same.
    AppTapInstaller.exe will fail, but your phone will get to the Activation Screen now!
    When on the activation screen, just follow my tutorial to jailbreak and bypass activation
    Now your phone main firmware is ok, but to get the phone part working properly you should also downgrade your baseband firmware. At the moment this is NOT possible if your phone already had 1.1.2 or 1.1.3 when you bought it (meaning it has the new bootloader). If you accidentally upgraded your phone to 1.1.2 or 1.1.3 and want to go back to 1.0.2 or 1.1.1, read on.

    Downgrade the baseband firmware:

    Set Settings → General → Auto Lock → Never
    Start Installer and install BSD SubSystem found in System Category.
    Go to Sources and tap edit and add http://i.unlock.no/
    Now install "Baseband Downgrader" found in Unlocking Tools category. This will take around 5 minutes.
    When done, restore your phone to get 1.1.1 firmware reinstalled.
    When phone have been restored, you can Activate and unlock as normal."

    So I'm asking you guys...Is this safe? Can I really downgrade if need be?

    iphone.unlock.no usually is a trustworthy source, and I've used many of their mods on my phone...

    But i have yet to find out if anyone has tried it...i'm hoping someone has already :)
