    Default Help need to unlock iPhone 3GS

    I bought the used iPhone3GS and was running perfectly with 4.0.1 jail break. But I upgraded it 4.1 and turned to problematic. It didn't show the carrier signals. First I tried to unlock it using limera1n but could not help out. Unfortunately that software works only with iPhone 4. Thus i again down grade it to 4.0.1 with iPhone2,1_4.0.1_8A306_Restore.ipsw restore software and run umbrella-4.02.09. Finally downgraded successfully but again the phone is locked and displayed message on PC as SIM card is not supported. Either use original SIM or receive a replacement SIM from supported carrier. Actually I don't know which operator was used before in this iPhone. While doing downgrade i could still see one saved shsh file named 3313467686319-iphone-4.0.2.shsh in my PC. is this useful to fix my Phone?
    Can anyone help me to get my original state? I searched in the internet and found that I can use PhoneBook SIM card. But I want to know that, does any alternative or any cracking software for it?
    Any suggestion will be great relief for me.
    Regards,
    Biky

    Limera1n is not an unlock, it is a jailbreak see http://www.hackint0sh.org/f137/32703.htm for an explanation of the key differences between these terms.

    There is no way to downgrade the baseband that you upgraded to when you loaded 4.1 - so you cannot currently unlock your iPhone.

    Apple has recently blocked activation using Phonebook SIMs, this was done on the server side - so it doesn't matter which iOS version you use. You need to hacktivate (redsn0w, greenpois0n, pwnagetool all support hacktivation - limera1n's hacktivation is not so good, but it should work for what you want)

    Hacktivation will only allow you to get past the "slide for emergency" screen.

    Hi friend Thanks a lot!
    I think my post is not clear so it made also confuse to you about my problem. Here I explain stepwise what i did silly thing

    step I: I upgraded my phone from ISO 4.0.1 to 4.1. Here carrier signal didn't appear.
    Step II: I restore the factory store and that I stuck in emergency slide mode
    Step III: I then downloaded limera1n and again get back screen to upgraded version ISO 4.1
    step IV: I searched in internet and found step to downgrade to 4.0.1 and downloaded needed files (iPhone2,1_4.0.1_8A306_Restore.ipsw and umbrella-4.02.09.exe
    step v: I proceed as the steps described and finally stuck up at the emergency slides. I tried with Limera1n here and again try to make DFU mode but end up with restore factory level.
    Now my stories continue, If i Understand your reply I can pass this stage using u mentioned software right? After that, can i unlocked my phone? Please can you explain furthermore.
    From different site I found that, Limera1n is only for ISO 4.1 to activate and unlock the phone. Cuz I tried again with Limera1n after downgrade but it couldn't catchup the phone and didn't work.
    Thanks

    Thanks Olethros
    As this site suggestion I read most of the discussion here in forum and found your one answer that TinyUmbrella will give iPhone info. I downloaded tinyumbrella-4.21.01.exe from this site and test with my mobile I found following Info:
    Saved SHSHs: iPhone3GS 4.0.2 (8A400)
    Installed Firmware Version 4.1
    Installed Baseband Version: 05.14.02-6.4_M3S2

    Now i am stuck at emergency slide mode and iTunes display info to use either original or compatible SIM. Now how can I get out from this problem. If i repeated my question I am sorry. I very new for this and don't know anything
    Your help is very appreciated.

    depends on the company of the phone
    if u bought from local Cellphone company then enter ur SIM card
    if not u need to put the orignal Sim card..
    u can Jailbreak the phone with the tools that in the net..
    since u 4.1 ur stuck with unlock now wait for unlock method when released..

    get SHSH for 4.1 asap
    Your only real option is to restore to 4.1 and jailbreak/hacktivate with redsn0w 0.9.6beta (you should be able to use 0.9.6b4)

    This will NOT unlock (you need to wait for new ultrasn0w, just like everyone else) but it will allow you to use the rest of your iPhone's functions until an unlock is available for your baseband version.

    There are no other solutions, don't waste your time trying other things.
