    Hi,

    i am new to this forum. i have a phone 3gs running on ios 3.1.3 (very old !!!). i need to update it to 4.2 or 4.3 (not jail break). I have downloaded the ipsw files for 4.3 and 3.1.3 (just in case). how do i go about upgrading the firmware. is it straight forward or do i have to go to a shop to get this done. (i read saying that on tunes shift+click on restore iphone and choose the 4.3 ipsw file and its done. is this true ?)


    I contacted Apple and they say to upgrade to ios 6 which i dont want to do because my phone is just a 3gs model and it will be sluggish.

    Any help please ?

    Thanks

    Plug your iPhone to your PC and open iTunes, click on your phone to view the specs and then click "Search for Updates" and when the update pops up, click install.

    the 3GS isn't sluggish on iOS 6. Just admit it, you want to jailbreak.

    I genuinely thought Apple doesn't sign another other firmware for the 3GS except for iOS 4.1 and iOS 6.0.1 now? There isn't any way to update to any other versions.

    Buy a 4. The 3GS scuffs and has "crackgate"

    Otherwise update to 6. Can't pick and choose your firmware for 3GS (unless you lie and jailbreak lol)

    Not sluggish, my friend had a 3GS (he recently just upgraded to i5) for like 2+ years and upgraded to iOS 6 when it came out. No problems. He told me it was fine, definitely not as quick as i5 but no slowdowns either.

    The most popular way is with a nail file hidden in a cake (at least from most movies I've seen).

    It will only allow you to change firmwares if you HAD been jailbreaking and had your signature handshakes from Apple's servers saved somewhere. Without those you will NOT be able to restore a 3GS to anything but the current one that Apple is signing.

    So had you been jailbreaking? If not, better head to 6.0 and live with it.

    Or sell it. That 3GS was an abomination with the plastic back and scratchy showing bezel (just kidding, it was a great phone, but the OCD folks are silly when it comes to cosmetics on the 5 all of a sudden).

    Then get a 4 (preferably a 5). FAR superior hardware.

    @cperchard - ofcourse i have heard of google but if you had been using google you would have know that it gives 1000 pages of results and on reading just 1% of those links, i bet anyone would get confused.

    if you would like to help, you can post the links (that would help and it is clear) on google !

    Sorry if I've been unclear, but: NO.

    The 3GS requires every update to be signed by Apple. There is a way to "fake out" the system, but only if you had been saving those signatures (by jailbreaking).

    Because you are on 3.1.2 without any of that information, your options are to stay at 3.1.2 (hoping that you never have to restore) and you CAN jailbreak if you want (just not to upgrade) or go to the current FW (6.0.1).

    Frankly, given that you haven't collected the info you need, you should just upgrade at this point and move on. In the event that your phone freezes and forces you to update, you won't have a choice anyway and will HAVE to go to 6, so you may as well now.

    You are correct.
    Only option is stay where he's at, or to 4.1 or 6.0.1
    No other choices without shsh blobs.

    I wasn't aware of 4.1 still being signed. That is great news for the OP.

    My mistake if that is the case. Forgot Apple was treating "legacy" devices slightly differently haha... good catch!

    Yes, its very weird but since September 2010 Apple still releases the 4.1 firmware shsh blobs just for the 3GS.
    I dont get why either:D
