    I have a iphone3G (not 3GS). My baseband is 05.11.07 and firmware 3.2.1 (7D11) unlocked to use a brazilian Sim Card (I bought in miami a locked Iphone).
    It’s writen that this custom 4.3.3 firmware works in 3GS (no comments about 3G).
    Can I upgrade my iphone with this custom baseband and have my Iphone unlocked and jailbreak? Does it cause problems in GPS like people told me that happens in another firmwares?
    Thanks for all .

  7. Leo says:

    If it’s possible for my iphone3g to use this firmware, which one i choose? activated or not activated? (info about my iphone is in the last question). Thanks for all.

    Hi i have ip4 bb 3.10.01 (4.2.1) can i upgrade my ios with this cf ?

  13. Shirin says:

    So my aunt got an iphone 3Gs and since I had an iphone 3G, I thought I’d help her out. Mine had 4.2.1 with baseband 6.15 while her’s had the same baseband, her ios was 4.1, I was just downloading a few things from cydia on her phone when I noticed an ultrasnow update. Once I updated it, the Sim was locked and the phone didn’t recognize any sim card. The locked sim worked on her old nokia but on her iphone so that problem was solved. I told her that it was because her ios was 4.1 and offered to jailbreak it to 4.2.1 and she happily agreed. I had jailbroken my phone only a few months ago so I knew how to doit (using ultrasn0w) but once I updated it in itunes, it entered recovery mode and has been the same ever since. I cant restore it because I keep getting an error. I don’t know WHAT to do. I feel soooo guilty now. The phone is stuck in RM and restoring gives error. Any ideas? Please do help if you can:)

    Hi there.
    I have an iphone 3gs on 4.1 jailbroken and unlocked with ipad 6.15.00 baseband.
    i want to upgrade my phoine to 4.3.3.
    I know i can do this with custom firmware pre activated n untethered.
    When i put my phone in DFU mode and try to shift+restore from itunes i get 3194 error.
    I obviously don’t have any SHSH blobs for 4.3.3 since neither cydia or tinyumbrella provides them.
    Does that mean i cannot upgrade my phone to 4.3.3?

  24. Micollo says:

    Hi I have an iPhone 3GS which has the DFU loop problem due to iFaith and I’m really stuck at DFU, I’m already fed up with it! If I choose to upgrade to the latest firmware say 4.3.5 cooked up in sn0wbreeze with preserved baseband and not jailbroken, will it boot my iphone and get rid of the DFU loop? I don’t care if it’s not jailbroken, I just want to know if it will boot up untethered?

    • Behzad.HD says:

      use ifaith v1.3.1 to fix stuck in DFU Mode
      ios 4.3.5 jailbreak is tethered & for iPhone 3Gs only can use Redsn0w that cant prevent base band update.
      so try to restore with ifaith…

    • Micollo says:

      Finally I got it fixed after days of DFU loop. I deleted any apple related IP address on my host file, ran iREB 4, downgraded to official 4.1, this time it kicked out DFU loop and went to iTunes recovery with error 1015, used TU to kick out of recovery reboot to verify DFU loop is gone, jailbreak with redsn0w, ran cydia, then launched TU again, point TU to download shsh from cydia, ran TSS server and used my cooked up 4.3.3 custom firmware with sn0wbreeze and restore. It finally restored to 4.3.3 untethered, no longwer having the DFU loop then unlock with ultrasn0w… I hope that helps XD

  25. Sami says:

    Well I have Iphone 4 on firmware 4.1 and baseband is 02.10.04 and I am currenlyy using Gavey Sim to unlock it,should i use this firmware and is it goin to keep me on the same baseband ? !!!

    • Nick says:

      i think you are good to go with this iOS but u need the unactivated version.
      But wait for a reply from others because i’m not quite sure.

    • Nick says:

      or maybe if you use the activated version you may not even need the gavey sim to unlock.But again i’m not sure :-)
