Unlock iPhone 3G/3GS Baseband 5.14.02 for Free with the New Ultrasn0w
There are a bunch of new iPhone users who are not very familiar with unlocking their iPhones using ultrasn0w. Therefore, the guide below will help you prepare when the new ultrasn0w is due for release anytime between November 22 and 24, 2010.
Prerequisites:
- You must have a jailbroken iPhone 3G or 3GS. We trust that you may have already done this either with Limera1n or Greenpois0n.
- You must have a working and stable WiFi connection on your iPhone.
Carrier Unlock Steps:
Before you start, remove the SIM card from your iPhone.
Step 1: Launch Cydia from the springboard.
Step 2: Tap on Manage.
Step 3: Search for ultrasn0w on Packages in Cydia. If you cannot find it, add new Sources by typing: repo666.ultrasn0w.com.
Step 4: A new ultrasnow package will be installed. Once done, go to Packages and look for ultrasnow. Tap and install it. During installation, you will see a black screen with running command lines.
Step 5: Reboot your iPhone and insert your SIM card. Toggle the Airplane mode to ON and then OFF. Your iPhone will search and register to your mobile phone network. Please be patient, sometimes it may take up to 3 minutes.
Congratulations! You have successfully unlocked your iPhone. If you encounter any issue, please leave your comments below.

hi, I have baseband 6.15, running 4.1 and it's fully jailbroken, on my 3g. I downloaded ultrasnow 1.2 and it won't work. it keep stating no service. I was able to get service for about 30 seconds on 2 occasions, but haven't been able to do so since then. I've read every forum and there are other people in my situation as well, but there hasn't been any solutions. Can you please help?
Thanks in advance!

Try restoring to 4.2.1 with custom firmware (download here: http://www.iphonejailbreak.me/downloads/), if it doesnt work, run redsn0w and reflash the baseband
i have now got baseband 6.15, running 4.1.2 and have installed ultrasn0w 1.2 and it isnt working, i am just stuck on 1 bar of signal all the time with no carrier being stated.
can you help?
try installing ultrasn0w again, and don't forget to install mobile substrate as well
I have a 3GS with new bootrom, 5.15.4 baseband and 4.2.1 firmware. What should I do?
this is your only possible solution for now: http://www.iphonejailbreak.me/untethered-jailbrea… then flash your baseband to 6.15 (might break GPS) and unlock with ultrasn0w
i have a 3gs – 4.2.1 – 05.15.04
i did the jailbreal using greenpois0n
then i did the unlock as u instructed, but it kept searching for a while and thenn said no service
what should i do?
baseband 5.15.04 cannot be unlocked, you need to use redsn0w 0.9.6 to update the bb to 6.15.00 (may risk breaking the GPS)
I am seriously an itard or just having bad luck. I cannot get my iphone to read my SIM, I've gone through the unlock process. I have Cydia loaded, and I have UltraSn0w installed.
Running 4.2.1 Version, The only thing I can get my modem firmware to say is 05.15.04. I cannot get it to update to 6.15.00
you need redsn0w to update to 6.15.00
I got my iPhone 3G 4.2.1 BB 05.15.4 first to fw 06.15.00 by following this article using redsnow 0.9.6rc16 and was then able to unlock using ultrasnow.
Was stuck at some places but google helped..
I am able to use the phone in India with vodafone now!!

is your SIM card active? Did you check if you have mobile substrate installed?
I have iphone 3g, 4.4.1 with 6.15.00 and again it is always searching. I jailbroke with redsn0w and unlocked with ultrasn0w. rebooted, reset settings, switched off 3g but still searching.Mobile substrate is installed ver. 0.9.3901. The phone does seem slow, and the display flickers a little as well as it constantly searching when I put in the sim. I am in the UK and I have an orange 3g sim. Any ideas
i have an iphone 3g. i jailbroke flashed to 6.15.00 and installed ultrasn0w it worked for a few hours than just stopped please help me.
