Thread: Best remedy for unlocked 3g with slow iOS 4??

  1. #1
    Default Best remedy for unlocked 3g with slow iOS 4??
    Hi everyone,

    I have been searching for the best way to fix my ridiculously slow iPhone 3g. I have been running iOS 4.0.2 basically since the jailbreak/unlock was possible, and since then have been waiting (like, with a burning --no, make that raging-- desire) for something better/wracking my brain to figure out what that something actually is.

    It seems that I could upgrade to 4.2.1, but is that any better? I would like to be able to run apps requiring iOS 4, but I guess I'd be willing to give them up if that's the only (bearable) option. I am nervous to try this because it seems I would have to use the iPad solution, which seems to be irreversible if it ends up sucking. If I should upgrade to 4.2.1, what's the best way to jailbreak and unlock?

    So, if 4.2 is no better, then I guess I would like to downgrade back to iOS 3.whenever-it-was-still-good. My baseband is 05.13.04, and the only backups I have are on iTunes and a blob from the current version. Can I downgrade? If so, then what, in terms of unlocking and jailbreaking?

    Yes, I'm a bit of a noob, but please don't dumb it down for me! Any help would be great -- Thanks!!

    I would advic u to downgrade. iOS 4 Is hardly bearable on a 3G and so 4.2.1 won't be any better..
    Downgrade to 3.1.3 by following these steps
    Download following things
    1) 3.1.3 ipsw http://appldnld.apple.com.edgesuite....8_Restore.ipsw
    2)Tinyumbrella. The Firmware Umbrella - TinyUmbrella
    3)Spirit Spirit

    After this:.
    1) shift restore from iTunes using the 3.1.3 Ipsw.
    2) u /might/ get a 1015 error .. If u get it use tinyumbrella exit recovery .
    3) activate the phone using the official carrier sim.
    4) run spirit.
    5) download ultrasn0w from cydia.
    Done !!

    You can custom restore to a whited00r custom firmware which preloads iOS 4 features but keeps it on 3.1.3 firmware. I'm not sure if the iPad baseband is also preloaded into the custom firmware...
    If I helped you in any way, please click on the button!

    looks like whited00r doesn't change the baseband...

    1) no . Higher firmware backups dont work on lower firmware..
    2) yes.

    for #2... even if i have no signal? what do i need to do? it's been waiting for activation for a while now...

  11. #9
    it really doesn't seem to be activating. is this a signing problem?

    also... somewhere along the way, my baseband has been upgraded to 5.14.02. does that mean i won't be able to unlock? now what??

    It's not possible that your baseband was updated if u followed what I said...
    Also can u access teh springboard?

  13. #11
    Hrm, I'm not sure... I tried some other things last night when it wouldn't activate. So now my baseband is 5.14.02, in any case. Does this change things, or should I just try your steps again?

    Then the phone is activated.. Don't know how u updated your baseband !!
    You are on 3.1.3 right ?

    Every once in a while a message pops up that says it's waiting for activation, even when I'm on my homescreen.

    I think the baseband thing probably happened when I tried to upgrade again because I forgot to backup my phone numbers. Now I am back to 3.1.3 --- do you still think everything should work?
