    ok so I have shsh blobs for 4.0, 4.0.1, and 4.1. I'm currently on 4.0 and I'm thinking about upgrading to 4.1. Is it possible to use tiny umbrella to upgrade firmware only without updating baseband? If so does this cause baseband problems? Also when I use TU to upgrade do I just select my shsh file or do I download something?

    Baseband updating really isnt a problem for me as i use att but if it helps in the future id like to preserve it....and without using pwntool.

    Thanks in advance!

    No, you can't preserve your baseband using TU on a 3GS, just restore to 4.1 and jailbreak with GreenPoison or Limera1n.

    You can only do it on Iphone 4 not 3gs.

    You are with ATNT anyway, you can either wait for New Pwnage tools to come out before you upgrade to 4.1

    I don't believe that is true. I have upgraded to 4.1 FW on a 3GS 16 and 32gb and preserved the BB. I followed the instruction as if I had an iPhone 4.

    Just update you can jailbreak with limera1n or greenpois0n. Since your with AT&T it doesnt really matter about the baseband.

    Wow, if this is true, then Tiny Umbrella far more superior than Pwnage tools and Snowbreeze in terms of preseving the basebands.

    I have a 3GS 32 gb that I restored to a 4.1 fw through tiny umbrella. I used the TSS server just like the guide for the iphone 4. Then I used limera1n to jailbreak it. I am currently on a 5.13.04

    That is interesting, thanks for the tip, I will also give you a good tip in return. The good news is that you have the oldbootrom and you can use custom firmware.

    Hi
    I got my iPhone 3GS 16GB upgraded to version 3.1.3. Jailbroken and unlocked. Now I like to upgrade it to version 4.0. I don't have SHSH saved. How can I do it, any help?

    I didn't know that you could preserve 4.1 baseband with TU on 3gs , he gave me a good tip, so I gave him back one.

    I need a second person to comfirm.

    It is possible he did it with custom firmware on an old bootrom.
    I can say the same thing too but I didn't use TU to preserve

    Tiny umbrella cannot preserve baseband on a 3GS. So he is obviously using a custom
    Firmware or has spoofed the firmware with cydia.

    I did not use a custom firmware. I use the guide recommended to preserve the baseband for the iPhone 4. I also agree that another person should confirm this. I do not know what impact having an old bootrom had for my 3GS.

    I recently upgraded from 3.0 to 3.1.2 using the Tss Server from TU and it upgraded my baseband for OS 3.1.2. Maybe it will just do 4.1 but i doubt it and I wouldn't try it cos I need the unlock.

    I wouldn't try it either as semaphore the creator of tiny umbrella has specifically said this method only works on iPhone 4. If you did use this method and somehow your baseband remained the same then count yourself extremely lucky, since there is nothing that tiny umbrella does that would affect installation of the baseband on a iPhone 3GS.

    I'll try it as I'm waiting for jbme2pwn just to upgrade to 4.1 and I don't "need" to unlock either but wouldn't mind keeping the 5.13 bb
