Unlock iPhone 3G 3.0 with ultrasn0w
Update: ultrasn0w has been released by DevTeam! ultrasn0w is an iPhone 3.0 software unlock for iPhone 3G users only.
Here is how to install ultrasn0w:
1. Jailbreak your iPhone 3G 3.0: use redsn0w
2. Go to Cydia and add repo666.ultrasn0w.com to your sources
3. Reboot your iPhone 3G (T-mobile users should disable 3G before using ultrasn0w)
4. Enjoy your iPhone 3G unlock, thanks to the Dev-Team that worked hard on it!
With the new OS 3.0 update a lot of people are stuck without an unlock, and they’re waiting for the iPhone Dev Team to create one. On Friday the iPhone Dev Team plans to release ultrasn0w. Ultrasn0w is the name of the Dev Team’s new iPhone 3G unlock software and it’s 100% free just like all the other Dev Team tools are. ultrasn0w will allow you to unlock your iPhone 3G on the new iPhone OS 3.0 firmware. Of course to unlock your AT&T iPhone 3G and install ultrasn0w you will need to jailbreak your iPhone 3G. The jailbreak does not appear to be out right now but Dev Team is working hard to bring it out for us. Please have patience and let the Dev Team do their work! Don’t ask when it’ll be out. I’ll make a post with download links and information on QuickPwn.com homepage, forums, and also update twitter, YouTube, send e-mail notifications to those who subscribed.
Waiting for ultrasn0w? Here’s what we know about it so far.
- It’s safe to update to the current iPhone 3.0 baseband – ultrasn0w will work with it, but for future updates such as firmware 3.0.1 (or whichever # the next firmware is) you should hold off on updating and check here first to see if it’s safe to update. Apple may be able to make a baseband update that permanently locks your firmware just as they did with firmware 2.2.1 users.
- ultrasn0w will only work with iPhone 3G – iPhone 2G users can still unlock their iPhone using BootNeuter
- Just like yellowsn0w, ultrasn0w can be installed from Cydia (Repo URL has not been announced yet)
More information and a guide on how to unlock iPhone 3G with ultrasn0w will be posted once Dev Team has released ultrasn0w!

i have the same problem! cant get my head round it! tried 2 different sims n they both eventually have no serivce! desperate for some advice!
i heard that ultrasn0w doesn’t work with the 5.11.07 baseband and by downloading and installing fuzzyband through cydia you can downgrade your baseband from 5.11.07 and it should work then, but idk i haven’t tried it yet because i can seem to find a wi-fi hotspot anywhere
I’ve tried this after I accidentally upgraded to the 5.11.07..it seems to have worked. When I go to settings the baseband shows up as 4.20.08 now.
but if anyone tries this and it works could you please reply

Jailbreak worked well no problems at all. Surprised it was so quick.

I have successfully jail broke my iphone3g with redsn0w,but not able to Unlock thru url-repo666.ultrasn0w.com it says DID NOT FIND REPOSITORY..is there any updated link available mow? can anyone please help me
You’re most likely a victim of the baseband and bootloader update. Search DevTeam’s forum or do a search for 3.1 firmware’s latest update and the problems with 6.02 bootloader.
Until someone @ Dev Team figures out a way to downgrade 6.02 bootloader for 3G, a lot of ppl are stuck and can’t downgrade so they can downgrade their baseband to successfully unlock.
ultrasn0w will not work with:
3.1 firmware, 06.02 bootloader, 05.11.07 baseband
Wait for the next hack folks.
iphone 3g 3.0 unlock
My friend asked me to unlock his 3G but he unfortunately ran the most recent update.
Currently his phone has:
Bootloader: 06.02 [G2M3S2]
Baseband: ICE2-05.11.07
OS: 3.1.2
I’ve got it jailbroken, but can’t unlock it. Hopefully they come out with a fix for people that are in this situation…
no work with bootloader 5.9
downgrade baseband
just go tocydia and do the upgrades one its done it says iphone activated and the no service goes away…good luckk….
PLEASE ADVISE IF THIS PROCESS IS WORKING PERFECTLY?
Try it and let us know!
no service wat should i do so it works base line 05.11.07
hi,
my iphone 3g 3.0 (4.20.08) is unlocked and im using orange UK sim. i tried other networks it says no service… but the unlock was not 100% if i switch off the phone and switch it on coverage never comes back… my solution is remove the sim from iphone and put it in another phone make a call then I put back to the iphone. then i will get the coverage… its realy annoyin…. im expecting a fresh release from ultrasn0w…
lets hope for it..
