Update #1: Go to my jailbreak iPhone 3.1.2 with blackra1n post to jailbreak your iPhone or iPod Touch!
Today the iPhone 3.1.2 update was released to iPhone, iPhone 3G, iPhone 3GS, and iPod Touch usres. This update includes mainly bug fixes. If you would like to jailbreak or unlock your device, you must read this. If you have an unlocked iPhone 3G or iPhone 3GS do not update to this new firmware, updating to the iPhone 3.1.2 firmware will permanently update your baseband. The newer baseband does not support software unlocking.
The jailbreak has not been released yet, but you if you’ve got too much time on your hands you may be able to jailbreak if you try the following. If this works please share your results in the comments.
How to Jailbreak iPhone 3.1.2
1. Update to iPhone 3.1.2. After updating, find your iPhone 3.1.2 IPSW file or download it using any of the links below. Remember, don’t use Safari to download. Safari can’t download .IPSW files properly, use a different browser!
- iPhone 3.1.2 download (iPhone1,1_3.1.2_7D11_Restore.ipsw, 241 MB)
- iPhone 3G 3.1.2 download (iPhone1,2_3.1.2_7D11_Restore.ipsw, 242 MB)

2. Download redsn0w.
3. Follow the jailbreaking guide at the Jailbreak iPhone 3.1 post.
Unlock iPhone 3.1.2
It’s possible to unlock iPhone 3.1.2 but only if your baseband has not been updated to 05.11.07 or the newer baseband, you must create a custom firmware that uses the 04.26.08 baseband. The iPhone 3.1.2 update updates the baseband to a newer one that permanently blocks the software unlock. A guide on how to unlock iPhone 3.1.2 will be up once a jailbreak tool is released.

Ok. So I have an Iphone 3g 8gb and it was unlocked. don’t ask me with what because i bought it like that. After I upgrade it by accident to 3.1.2 version i wasn’t able to use my sim card anymore. tried to unlock it using blackra1n and co. but no luck. Being desperate I gave my phone to a friend who was going to philippines and she came with it unlocked. Any ideas on how they did it??
Ps: I live in denmark and I m not able to use it with telia but it works with Lebara or other carriers
just go to the Philippines and jailbreak it here ☺
i have an iPhone 3G 16GB, i just updated it in itunes and i was able to use any sim card, the real problem is jailbreaking your iphone, im curious if your iphone has been jailbroken also.
P.S.: i live in the philippines. ^^
Its simple, your iPhone is only unlocked temporarily and once you completely turn off you iPhone its going to get bricked or they used blacksn0w which you can download from cydia.
I used blackra1n and reboot. Then i run the app, but i cant install cydia or rock. it says please check your internet connection. but wheather i use 3G or wifi, it doesnt work
hi i ussed blackra1n and it jailbroke and i got cydia and i wanted a theme so i downloaded a theme and it said reboot system and i did and it said connect to itunes but itunes would’nt recognize it then i had to un-brick it then the same thing happened wtf!!!!! help plz
Same thing happened to me! I cant use my phone at all and I’m freaking out….
It happened to my iphone also.. since i was playing around with it [iphone 3gs 16gb]
try run black ra1n again and when the message that says that your iphone is jailbroken press ok, keep the blackra1n window open and wait..
this is what happened to me and it seemed to work for me..
when u turn it on again just dont restore it jail break again.just push that make it rain
Hi danny before downloading the theme you must download winterboard and the mobile substrate which protects your springboard when it crash any way try it you will get
Relaxx this unlock is only temporary, there still coming out with a new one. This happensto every one. Try using blacksn0w, install it via cydia andthen try turning off you phone too see if it bricks.
I used this with my iPod and it worked great! Don’t really understand alot about the rock and cydia apps yet but I’m getting there! But overalll it applied perfectly.
When u unlock with blackra1n and u have Cydia download sbsettings when u set the theme use sbsettings to respring ur phone don’t reboot u can’t let ur phone die or reboot with 3.1.2 or u will have to rejailbreak it also I’d reccomend downloading the terminal app to change ur admin password and rock becuz it’s a better download tool than cydia and for not being able to use ur sin after upgrading u may need to restore ur phone with iTunes and jailbreak it over again for it to work These answers are based on personal experiences and messing around with different options I had the same issues

Hi, so…how do I find out what my base band is.. :?
I have version 3.1.2
ok, nev mind, figured it out.. :)
Hi.. I’ve download the bootneuter,but the process when determining current setting is very long. So I break the process. Does it the process is always long like that or not? Then what’s the effect when I break the process? Then what should I do next? Thanks :)
hi i have an iphone 2g with 3.1.2 firmware unactivated because i updated with itunes i recently had the problem but was able to activate it when it was 2.2.1 firmware by using quickpwn but now i cant and its stuck on “connect to itunes” lockscreen and i cant get the proper carriers coz i live in dubai plz im desperate 4 help
You have to restore it using an ACTIVATED firmware.
Which is the same as any other firmware, but can be used with any other carrier.
Hiii I used blackra1n and it just got stuck on the connect to iTunes screen. I don’t get how I jailbreak it if it gets stuck on that screen. Please help!!
Same with me !!
What do I do ??
u got new iphone 3gs? if so its untethered which means every time you turn your iphone off and then back on you need to re-unjailbreak it. this is true with newer iphone 3gs and newer ipods. So in order to get past your connect to itunes screen you have to run blackra1n AGAIN. and anytime you turn it off (which you should try avoiding) in order to turn it back on you have to use blackra1n.
*re-jailbreak

I currently have an unlocked (and jailbroken) Iphone 3g running on the 2.2 firmware. It is at the point now where many apps no longer work with the older firmware and so I need to update this, However, I see that if you have an already unlocked Iphone that you should not update to 3.1.2.
Can someone please help!
i have i phone 3gs 3.1.2 new and everytime i jailbreak it it ask me to do it again on every exit is the any solution for this problem?
Hey there,
Would love some ones insight..
I have an iPhone 3g with 3.1.2 and firmware 05.11.07. I have downloaded blackra1n to jailbreak and it worked great. But I am leaving to Hong Kong soon and I really hope it will work as an unlock too.
I leave in 2 weeks and I really want to use it in HK with a prepaid sim.
Hey guys! Need some help here. I have a 3G iphone version 3.1.2 (7D11) and 05.11.07 firmware. I’ve downloaded Cydia (jailbroken) using pwnage and tried to unlock it using ultrasn0w on cydia. But it won’t work…tried it about 3-4 times, still no luck. Any suggestions? Now that I already have Cydia, should I try using blackrain to unlock it? Please advice.
Does anyone know what to do?
I successfully installed the blackra1n (raindrop) app with no problem then deleted it. Now i cant get it to install at all, i’ve been trying for hours. I know i should restore my iphone 3gs and try again but every time i try, Itunes give me the error message: “..this device isnt eligible for the requested build.” so i cant restore i dont know what to do.
By Mistake i have updated by jailbrek i phone 3g 8gb to os 3.1.3…
i tried blackra1n but i am unable to make it run…please give me solution what to do….
Hope this works cause im pulling my hari out!! ;-)
