Select “ra1n” to upgrade BlackRa1n to RC3. After upgrading, run BlackRa1n and you should see the “sn0w” option. Just select “sn0w” and it will unlock your iPhone.
* If you were waiting to update to 3.1.2 or if your iPhone was stuck locked, then download BlackSn0w, run it, reboot, and choose the “sn0w” option from the BlackRa1n.app.
* If your iPhone was previously jailbroken using PwnageTool or if you deleted the BlackRa1n.app from your iPhone, BlackSn0w will be added to Cydia later during the day.

Hi,
I installed blackrain RC3 and unlock works fine, only with a reboot the iphone comes in recovery mode. With the iphone connected to itunes and de blackrain jailbreak open the iphone starts up.
When i disconnect te cable to the PC or MAC, the iphone keeps comming in recovery mode.
SW 3.1.2 (7D11) Modem 05.11.07.
Someone has a tip to solve the problem ?
My workaround is to connect the iphone to PC or MAC whith blackrain jailbrak open. Then the iphone boots without going to recovery mode.
Even wifi is working.
Kind regards, Edwin
I have the same problem with my iPhone going to recovery mode on reboot.
Any solution for this yet?
I haven’t found out anything yet, pls keep me posted if you find any solution around.
Have you heard any answer yet? I am able to get into recovery mode finally and now restoring. I used RC2 before and did not have this issue. But once I ran RC3 to re-jailbreak, I get into this weird issue again. Resetting the network makes it worse.
Does anybody knows what happen if I unlock my iPhone with this software and I update the firmware with iTunes when Apple release a new one? thanks !!
can any body help? i have jailbroken i phone 3gs 3.1.2, i have installed new docks but it wont let me change it :S ive ticked it in winterboard but it still dosent change… can enybody help me with this? i have downloaded themes, lockscreens, dialers etc with no problems and used them fine.

I try to switch to ON, but the little idling star comes up, and it switches back to OFF.
Can someone please help? Thank You
Thanks to @geohot ..sn0w did the job for me..!
Will blacksn0w unlock my 3G iphone with firmware version 3.1 (not 3.1.2) on baseband 5.11.07? i updated to 3.1 when it first came out (but never upgraded to 3.1.2) and was able to jailbreak but not unlock, i have cydia so if i add the blacksn0w resource and install, will it unlock properly?
I jailbroke and unlocked fine, but iTunes says “The sim card in this phone does not appear to be supported.”
What can I do to fix that?
I just got a second 3GS today and unlocked it the same way and it works with iTunes. something must have gone wrong with the unlock on the first one..
Which USA carriers will work for an unlocked 3GS? The jail break worked perfectly. Would consider the unlock but which network is the best alternative?
hi guys i dont have any network even i reset my network setting several times?plz help
For some reason when I insert the sim it wants me to connect to itunes and it then says there’s a problem with the iphone and to contact apple. I’ve read that the iphone needs to be activated with the original sim or something like that but it was bought second hand and I don’t have the original sim. Any ideas??
OMG thanks sooo much. I have been trying to unlock my phones for AGES. I did both mine and my husbands (3 phones all up) and the only hint I would give is once you download the .exe file use it to jailbreak/unlock one phone then delete the file and download it again for the next phone. I initially tried the same .exe file for the 2nd iphone and it wouldn’t work. Once I deleted the original file and re downloaded it, it worked fine.
THANKS AGAIN – ONE VERY HAPPY GIRL!!!!
I jailbroke and unlocked my Iphone 3gs 3.2.1 with 5.11.07………
MOST of it works. I had to use the “push/wifi” fix to get the wifi back and I have signal MOST of the time……….but after not using the phone for a while, when i either get a call or make a call, the call will “fail”, then the signal goes, then the “searching” appears then the signal comes back strong……..then all the other calls within a reasonable amount of time are fine………if i don’t use the phone for another hour or so, the same thing happens again………
……ANY SUGGESTIONS?
THANKS,
i cant get youtube to work after unlocking and jailbreaking my fone with blackrain ..Have i done something wrong
Check this out: http://techpp.com/2009/11/18/gps-wifi-youtube-fix-after-blackra1n-jailbreak-unlock/
i am not able to install blackra1n …kindly suggest
OMG! I am not very experienced at all at this… I actually paid to have my iphone unlocked previously and decided it was time to teach myself… there were a few little things like the blacksnow freeze up which i hit the home button and tried again (per comments from others) and it worked perfectly..my phone is on t-mobile running 3.1.2 with no problems.. I will definitely donate.. All I can say is WOW! If I can do this anyone can.. keep the info coming!
I cant seem to get the unlock to work on this Rogers iphone 3G. When we insert the new SIM card from Bell we get a message asking to connect to itunes and then it says theres a problem with the phone. Am I missing a step? Does the new SIM card have to be IN the phone when I run blacksnow? I also noticed that if I go into the About section of my iphone it says Not available for the carrier. I checked on a Bell iphone and they have Bell 5.1 listed for the carrier. Any help would be appreciated! Thanks!
I unlocked my phone using blacksnow and jailbroke using blackra1n rc3. The jailbreak worked without any issue. After unlocking the phone I put in a tmobile sim card and I have not had 3g coverage or the internet. No safari nothing. Its been nearly two weeks. I have tried the network settings reset. Wifi works fine but anytime I try to connect to internet or facebook it says no data package but I am paying for data package. How can I fix. Please please help me.
Okay i accidentally uninstalled blackra1. Is there any way to get it back on my iTouch without restoring? Thanks. Please help
Works great! I just unlocked my phone and my ROGERS sim is working! woohoo!!!
Ok, I have read here where many have had the same problem after jailbreaking with 3.1.2 firmware on a new iphone, instead of booting it goes to the apple screen for a second then into recovery mode with the itunes and usb cable picture on the screen. Only way to boot is run black rain on the pc while cable is connected to iphone and phone will boot right up. Why? Why will the phone not boot on its own? This doesn’t do any good if you have to repower your phone while away from home. I have seen 10 comments on here, and I would LOVE for someone to address this. I really like having my phone jailbroken, but I have to have it boot up without the assistance of my pc and blackra1n. Please help. thanks. J
its the ne iboot thats been installed by apple in ne iphone to help deter people from jailbreaking, there is no fix as yet so every time you turn the phone off or reboot you will have to connect to comp and run blackra1n again!
sorry but i guess a fix will come in time x
blackra1nrc3 will work for you… just restore your device from itune(shift+restore) and run blackra1n…. if u have wifi&youtube problems… reset network and download push/fix from iphoneil repo… everything should work… thank geohot for the great job…
After much research, the jailbreak on a new 3gs with 3.1.2 is “tethered only” at this time which means that you have to have it hooked up (tethered) to your pc with your usb cable and you must run black rain each and everytime you wish to boot your phone. That sux, but it is a fact right now, no other choice if you want it jailbroken. Word is that development team will have an untethered JB eventually. So I am sticking with the tethered break and hope I can just keep my phone on all the time.lol
I downloaded and went to install but when it got to the reboot part. no picture of the guy came up and it was just a blank screen and never ended up restarting.
why?
Hey i have a problem where my service go’s in and then out, fluxuation, then NO SERVICE, then again! and theirs many people with this same problem! but i NEED help, its very anoying! lol.. but either way, i wonder whats wrong.. reseting network setting does not fix it! i need SOMEOTHER thing tp try maybe?? any ideas?
HELP “no service problem”
very easy, worked perfectly for my iphone 3g upgrade to 3.1.2 firmware and 5.11.07 baseband. now i can use my iphone with other network. it is very important that you have a working wifi, because after jailbreak with blackra1n, you need to download cydia and blacksnow in you iphone. i had a hard time unlocking mine because of the wifi connection in my area.
i unlocked my phone using blackrain, but now i dont know how to get cydia on my phone. does any body know wat i can do step by step???.. i cant seem to figure it out!!!
I accidentally updated my IPhone with iTunes at version 3.1.2. I bought it second hand and it was already unlocked. After I updated it it worked for 4 days and then all of a sudden I didn’t had signal anymore. I tried to unlock it using blackra1n, downgrade it to 3.1 and then unlock it, update it again and try to unlock it. All in vain. I don’t know what method the previous owner used to unlock it and I am kind of desperate to unlock it, because for the moment it’s just an expensive iPod. Please help…
