    Hi everyone,

    my sister has an iPhone 3 with ios 3.1.2 7D11, pretty old, eh!

    I would like to update it to, say 4.x, but definitely not to 5. Is it possible ? I tried to google this but didn't get relevant info.

    D.

    She can only update it if she has her SHSH blobs. If she doesn't, iOS 5.0.1 is the only version she can upgrade to. Use TinyUmbrella to see which blobs she has.

    First of all what is an iphone 3?
    You're talking about an iphone 3G or 3GS?

    Well, there is only "iPhone" in the back, so I presume original iPhone, right ?

    A1303 (weird, if I put only "A1303", preview translates first char in lower, this comment will keep it in upper)

    You have a 3GS phone. So, if you hook it up to Itunes and do update, it will update your phone to 5.0.1. However, Apple still sign 4.1, so you can upgrade your phone to 4.1 only if you don't want to go to 5.0.1

    No. Are you planning to keep your phone old baseband? if you don't need to, all you need to do is as follow.
    1. download 3GS 4.1 fw to your computer.
    2. Hook your phone to PC, open Itunes, hit shift + restore at the same time, then point it to 4.1 fw you download it earlier.
    3. Itunes will restore/update it for you.

    The reason you can do this is because your phone is still at 3.1.2, so this is an upgrade and you do not need to put your phone into DFU mode.
