    Hey Guys,

    My iPhone is a bit slow (3G) on 4.1 so I wanna downgrade to 3.1.3 if I can.
    Just wanted to check how I do that.

    Can I put my iPhone into DFU Mode and shift-click and install 3.1.3 using something like redsn0w?

    My SHSH's are saved on cydia.

    My Baseband is 06.15.00

    Cheers for the help.

    Hello all. First post!
    I want to ask if 3.1.3 is that much faster on the 3G than 4.1. It takes about 8 seconds to open messages. That's ridiculous. Pls let me know.

    Sync99, its easy. I will send you a PM with a link to downgrade from 4.1 to 3.1.3. Even without SHSH blobs it seems.

    Yes, for 3g, peak performance is at version 3.1.3 same for 2g, because 2g and 3g have the same speed and Ram resources with just the added GPS feature.
    Download Stock 3.1.3.
    Put iphone into DFU mode.
    Run itunes > Shift + restore to 3.1.3 ipsw.
    Error 1015 pops up.
    EXIT recovery to kick it out from the feature of Tiny Umbrella.
    Now you are at Emergency screen > ( You don't need any sim card in there )
    Run redsn0w 0.9.4 and browse to stock 3.1.2 fw which you have to download too.
    When finished, you are jailbroken at 3.1.3 .
    Update Cydia and install Ultrasn0w to unlock your Ipad BB .
    All Done, sit back relax and if you are above 21 in US , you can drink a beer

    That's close to what I did except I have an AT&T sim, so I let iTunes activate it. Then I used jailbreakme.com to jailbreak it over my wifi connection. Ater that I inserted my T-Mobile sim turned off 3g and installed Ultrasnow via Cydia. Worked like a charm.
