    Default Optimal upgrade/Jailbreak for 3.0.1+blackra1n

    Hello all,

    I currently have a 3gs with 3.0.1 (haven't gotten around to updating in forever). I was considering jailbreajing it. I also recently heard that apple stopped signing the 3.1.2 firmware. My question is of it's somehow possible to upgrade just to 3.1 (or will iTunes not allow me to load an older firmware than 3.1.3 now?) to get the native MMS, then use some older version of blackra1n to avoid the tethered jailbreak?

    In short , since I don't have the new baseband, could I end up with a non tethered 3gs with mms somehow?

    Sorry if this has been covered before, didn't find anything similar...
    Thanks for any help!


    Thanks!

    Moved to 3GS section...

    Okay, lets start with the most important thing. Have you backed up SHSH blob for *any* OS before OS 3.1.3? You are aware that you can do this without jailbreaking via The Firmware Umbrella.

    If you have not done this yet, it's too late (even if you had just thought about *maybe* jailbreaking you should have grabbed your SHSH blobs for 3.1.2. All Apple will give out now is a SHSH blob for OS 3.1.3. Right now there is absolutely no use in a 3.1.3 blob but there will be a point in the future...

    Now onto the positive news
    As you have a 3.0.1 3GS you don't need to worry about tethered jailbreaks.. This is only a problem with 3GS iPhones made after September last year.

    You have the 3.0.x baseband and you should try very hard to keep that (even if you don't unlock) the 3.1.x baseband has had more reports of wifi problems (even for people who don't unlock)

    It is not too late to jailbreak your existing 3.0.1 with redsn0w.

    Once jailbroken, you must always use custom ipsw (created with pwnagetool) to load 3.1 or 3.1.2

    You just have to be very careful to never let iTunes restore or update to an original iTunes IPSW.

    The slightly bad news
    Without a SHSH blob you have no safety net and that means you need to be more careful about what you install or update within Cydia (some things can cause your iPhone to be stuck at the apple logo and never boot)

    Back to the even better news
    You can get native MMS on a 3GS from iPhone OS 3.0 without jailbreaking - if you are with AT&T you might not have been notified of this if you were not running iPhone OS 3.1 or later but you can still manually load the updated ipcc that contains MMS settings on your 3.0.1 phone.

    So it is not all that bad really and it is great if you backed up a SHSH blob for 3.1.2 or lower

    Olethros,

    Thank you! That was probably the most helpful reply on a technical forum Ive gotten...well, probably ever. Unfortunately I dont have my SHSH for anything 3.1.2 or lower. Sucks that I got on the firmware umbrella train late but I just used the umbrella to create an SHSH (not sure what you called it blob?) for my ECID and 3.1.3 just in case it gets jailbroken eventually. I also downloaded the ipcc you suggested as well. I went with the non tether as it seems that pdanet is a better option (or so ive read).. I am now ready to jailbreak...

    Unfortunately Im running a PC...I guess this means that after I jailbreak the only thing I need to do is find a custom ipsw made by someone who had pwnage tool and download it?

    Basically...

    To use custom ipsw ive downloaded, would I still need the corresponding SHSH file for that version?

    Should should use redsn0w 0.9.2 instead of blackra1n as blackra1n can affect the baseband?

    Also, using the method of storing the ECID should I still capture the iBEC and iBSS files?

    Thank you so much for the help!
