  10. Hi,

    I recently got a new iphone 3gs. It was running firmware 3.1.2 and I unlocked it using blackra1n. I accidentally updated to the 3.1.3 firmware on baseband 05.12.01. It relocked the iphone and I have no idea how to unlock it. Please help me, I'm desperate to get it unlock so I can use it again. Thanks.

  11. @Landri
    It's possible to unlock and jailbreak your iphone 2g. Go on google and search up iphone 2g 3.1.2 firmware. Then put your iphone on restore mode (Don't know how, search up on google).
    When on restore mode, (PC = hold shift button and click restore and locate your file through that way.) (Mac = Option + Click and locate your file through that way )

    Then you can jailbreak it on 3.1.2, need more help, email me at [email protected]

  12. Hi Guys!!
    Just wanted to let you all know that there is no solution available to jailbreak 3.1.3 at the moment. If your iphone is already jail broken then and only then you can downgrade your phone otherwise dont try any softwares at the moment as it wont help… iPhone 3Gs restore option checks the firmware version from apple server so there is no way you can by pass that .. there is a mirror server available but I tried it ..doesnt help … you can edit your host file by adding this mirror server [74.208.10.249 gs.apple.com ] … but this doesnt help as well …

  13. So the process above doesnt work.?

  40. Currently there is no solution on unlocking 3.1.3.. You all have to wait for proper hack..

    I heard that proper hack will be released after iPad is launched, i.e. at the end of March or in April..

    So, try to avoid updating to 3.1.3.

    -Mahesh.

  41. There is no way you can unlock your Iphone with the firmware 3.1.3 (base band 05.12.1). The dev team has already got the unlock, but they are not going to release as early as the 4G Iphone comes to the market!

  49. sorry…..my above comment was meant for MIKE C….

  50. I can say that this method has not worked, I just have "searching…" where the signal bar would be.

  51. "There is no way you can unlock your Iphone with the firmware 3.1.3 (base band 05.12.1). The dev team has already got the unlock, but they are not going to release as early as the 4G Iphone comes to the market!"

    I accidently updated my 3G to 3.1.3 also. But we can't do anything now. All we need to do is just WAIT :) So if you have an extra phone just use it first.. &I heard that 4G iPhone might come out during May-June? Who knows, so let's pray for the dev team to release the 3.1.3 ASAP (:

  52. Mike C posted it on april first people pay attention!
    dev team's got it but they haven't released it yet so for now all we can do is sit tight and wait till they do -.-

  53. To all!!!!!
    Dev team u guys should release
    The 5.12.01 BB now
    Because why do people want the 4G iphone and still running EDGE on t-mobile. That"s is 3 times. FasterAbb
    I don't want to use a 4G iphone running on EDGE network!!!!!

  54. i have 3 G mobile i installed the version 3.1.3 after that it was working since it fell down on floor and sensor screem was broken and telephone still working properly when i sent it to replace the sensor screem they call me and told me that my phone have no signal till now it,s working but if i put my sim inside it there is no signal .

  60. Hi,

    I have the same problem as many of them. I have the iphone 3gs, i originally bought it unlocked to the 3.1.2 software using blackra1n. I accidentally upgraded the software through itunes to 3.1.3 i believe and I was wondering if there is anyway it can be unlocked any time soon or if i can downgrade back to 3.1.2 software? Just please help, it would be great!

    thankyou,

    jean

  61. Ya know? If more of you did your research you would see that there is no unlock for the 05.12.01 baseband, and there wont be one till july of june when the 4g comes out BECAUSE they dont want apple to find the exploit and fix it. The 3.1.3 update is a very small update, the update for the 4g will be huge and THAT is when they are going to release an unlock so just chill till then, the world is not going to end because you cant call your friends on your iphones. It sucks but complaining about it wont make the update come any faster.

  62. hie..i have lock my iphone 3gs…n dat goin 3.1.3 version..so gimme some sollution….

  68. unlocking of iphone ver 3.1.3 may be available upto 1st May 2010 inshALLAH

  69. I just bought an iPhone 3gs 16gig from a friend. I put my sim card in and it connects to my service provider no problem. Its on ver 3.1.3 and BB 5.12.01 and is an "MC" model. The phone seems unlocked to other networks, can i go ahead and attempt ONLY a jailbreak (No unlock – as it is working on my SP) or will it lock the phone? anyone know?

  70. I think we have all this problem with 3.1.3 and i dont see a solution yet i just use the i phone a a very expensive i pod

  71. I realized that the phone needed to be downgraded. Go to Cydia and search and install 'fuzzyband' hit downgrad and it should downgrad your baseband to 5.08.
    Once I did this. It took maybe about 5-10 minutes to receive text messages that a friend had sent me a while back. I didn't even to continue to downgrade the firmware from 3.1 to 3.0. As I had originally had planned on doing. For full details go to link below. Hope this aids everyone here!!!

  79. I am also waiting for the unlock to come out. However, i knwo that it is not available yet and if you have read this thread you should know that too – im bored of reading people saying please help me unlock my phone – you CANT UNLOCK IT YET!

    As most some people have said – they probably wont release until version 4.0 is out. If they did then v 4.0 would no doubt fix the exploit and then we'd have to wait for a 4.0 fix too!!

    Be patient

  117. Hi Have purchased iPh 3GS without contract.

    pls reply as soon as u can…………….

  118. @Umer i am not able to go past the emergency screen section in i phone it is a new one if i put a sim and connect to i tunes it says no service avilable

    I think i have 3.1.3 and 5.12 base band any help guys

  119. @ KIRAN

    It means that you are not even jail broken what to talk of being unlocked. The simplest thing to do is search for Customized 3.1.3 OS on google.

    Download it.

    Go into recovery mode.

    Press shift restore.

    Select the file that you downloaded and restore your phone from it.

    After completion it will reboot and be recognized by itunes.

    It will at least be jail broken and you will be able to sync to itunes and use it like an ipod touch.

    Till date there is no unlock available for 3.1.3 5.12.01 so you will just have to wait till the time it becomes available.

    Cheers!!!

  120. @Umer,

    I am using the phone in India and I did just what you have said in your last post. But my phone gets stuck at – 'Insert a valid sim'
    Now is it that I can jail break only with an AT&T sim??? I don't have one with me.. :(

  121. @ SWAPNIL

    A good idea is to go to a shop that unlocks phones and tell them that your phone came with an AT&T carrier. They might have a sim with them. This would be the simplest solution for you dude

  122. its look like a lot of people are wit 3.1.3 firmware and 05.12.01 baseband (like me) sh…t we are doomed.
    apple are idiots.
    in 2010 they stil lock iphones.
    f….. bastards.

  123. same as @umer, i am also facing emergency call screen after updating my firm ware to 3.1.3 from itunes and i bought at&t sim from my friend who came from US, then also it shows invalid sim. is there any solution to this

  124. @ BABU

    Hmmm that is really strange. With an original AT&T SIM it should have been recognized in Itunes.

    I guess the only option for the time being is jail break and wait for the unlock to come.

    I have already explained the jail break method in one of my posts earlier on

  125. all i can say i F……………………apple.Dev team help us soon……………………we need you guys.

  141. @umer Bangalore India

    do not want to risk anything so waiting for the unlock version for 3.1.3 to come out desperatley

  142. @ KIRAN

  152. Hi guys please consider helping me!
    First off my uncle is going to KILL me if he finds out what happened to my iphone! So this is the story…
    For a christmas present my uncle gave me an old used iphone(the original one from 2007) and he told me not to put a sim card in or else it would lock my iphone! So the next day i downloaded a new itunes version because i wanted to be able to download apps and it said i needed a newer version. I forgot what version it was though. So i was finished downloading it and then when it finished it said "insert a sim card" and it locked. So today i went to Walmart and the electricician guy gave me a sim card and told me to go home and go on to itunes and follow the instructions it gave me. So i got home and i went onto itunes and it said a bunch of things about connecting it to at&t in order to go on. But the thing is… I am not aloud to have a phone yet and my mom said that i cant connect it to any phone network and she wont change her mind! And so i canceled it and my iphone now shows a lock symbol at the top and itunes with the cd thing (logo) and a cord next to it. What should i do to unlock it! NOTE: keep in mind i cannot have a phone but i want apps! Also MY UNCLE IS GOING TO KILL ME! PLEASE HELP ME!
