    Hi just wandering how best to upgrade my IPhone 3gs I'm currently on

    3.1.3

    05.12.01

    I have it jailbroken already but my apps seem to close and they wont allow me to open them this all happened after updating cydia, which is why i thought i would upgrade my phone then jailbreak it again but I'm unsure of the best ways to do this

    I was hoping to use jailbreak me but it says don't update past 4.0.1 which is not a problem but after hrs of searching i cant find the firmware 4.0.1 as i presume updating with itunes will update to the latest which i wouldn't then be able to jailbreak

    any advice please???

    thanks

    Firstly you shouldn't use 4.0.x on iPhone 3G, if anything you should use 4.1 or 4.2.1. Although 3.1.3 is probably best for the phone in general.

    Of course jailbreakme doesn't work on 4.0.1 or higher, but you really really shouldn't use that firmware.

    If you decide on what firmware you want to restore to, let me know and I can help you.

    Yep. Whenever there are problems with a device, I like to restore to a fresh clean stock firmware. Then jailbreak after. It's very simple.

    Go download a stock 3.1.3 ipsw (Scroll up, click Downloads > Firmware) for your iPhone 3G

    All you have to do now open iTunes, hold shift and click restore. Browse to your 3.1.3 ipsw, and let iTunes restore your phone. Now if you have things you want backed up, do so manually.

    For contacts, the info tab in iTunes, select your backup option there. For Apps, right-click device in iTunes and select "transfer purchases." For photos/videos, be sure to back those up manually. In Windows, My Computer > click your device, you'll find your photos in there, move them all to your computer. Note: your photos and videos can be synced back into your phone, but it won't be able to be deleted from your phone unless you sync them out.

    You should write a list of your jailbreak installations if you'd like to re-download the same things after you restore and rejailbreak. I don't trust backup apps for jailbreak packages, but that's just me.

    When you do your restore, just make sure after you don't restore from a back up and you set up as new. Doing so will greatly reduce your risk of having the problems you're experiencing now return.

    He wrote that he has a 3GS iPhone, not a 3G. The upgrade to iOS4 wouldn't slow his phone much.

    Are you still going to stay on iOS3 (3.1.3 firmware)?

    Hm. Well thanks for pointing that out. That "s" is so hard to see

    You can't restore to 3.1.3 with what I wrote out unless SHSHs are saved for the device. 4.3.3 is likely to be the firmware you'll want to go to then. Via custom firmware if an unlock is necessary. If no unlock is necessary, a straight upgrade and jb with redsn0w will do.

    Yeah sorry, that was my mistake. You need SHSHs for 3.1.3. Did you want to restore to 4.3.3? It'll be fine with an iPhone 3GS.

    Without the proper SHSHs saved, you will not be able to downgrade.

    Example) I can downgrade down to 4.1 because that was when I first jailbroke my 3GS.

    Anyways, as iAnnie posted, unless you have the SHSHs, upgrade to the latest firmware and jailbreak from there on in.

    Yes, download 4.3.3 firmware and redsn0w. Open the program and it will guide you through, the instructions are K.I.S.S.

    SHSHs can be saved only when the current firmware version is signed. If SHSHs were not saved while whatever firmware you're looking to restore to then it's too late to get them. You should check to see if you have them saved if you've jailbroken the device before.

    However, I think you can safely get to 4.3.3 and be ok. Sn0wbreeze for Windows or PwnageTool for Mac is what you want to download. And a stock 4.3.3 firmware.

    Download the most recent version to jailbreak firmware 4.3.3 Dev-Team Blog

    With this you can create a custom firmware to restore to!

    I hope you preserve your baseband if it's an unlockable baseband!

    Alright, here's a crash course:

    Your baseband is essentially what will determine whether your iPhone is unlockable via software unlock or not.

    The issue happens when you decide to update your software. If you previously had an unlockable baseband but you happened to update without using a custom firmware then you are stuck and cannot downgrade to an unlockable baseband (you can downgrade firmware but that will not alter your baseband version).

    When you want to preserve a baseband you can make your own firmware (or download one) that will update everything except your baseband, hence you will keep your software unlock.

    I hope this helped!
