The iPhone Dev-Team has announced an update to UltraSn0w that makes it compatible with iOS 4.3.1 for basebands previously unlocked.
We’ve pushed out the 4.3.1 compatibility fix for ultrasn0w in Cydia — it’s now at version 1.2.1. If you’re not already at 4.3.1 and you need the unlock, please be sure you understand how to get to 4.3.1 using a custom IPSW that doesn’t update your baseband. There are lots of guides for this (like at iClarified.com).
This isn’t a new unlock! It’s to allow those who are already unlocked to use FW 4.3.1. It also fixes the signal bar issue for those who aren’t using the unlock but retain an older baseband intentionally.
After installing UltraSn0w 1.2.1 you should reboot your device by using the normal power button and "Slide to Power Off" swipe. USA T-Mobile users need to disable 3G mode in Settings:General:Network.
To upgrade to iOS 4.3.1 without upgrading your baseband you can use one of these tutorials ● TinyUmbrella iPhone 4 (Windows, Mac) ● PwnageTool iPhone 4 (Mac) ● PwnageTool iPhone 3GS (Mac)
I have a iPhone 3G (originally on Orange France) and wondered if I could unlock it. Jailbreaking is no problem but unlocking with UntraSn0w doesn't seem to work:
iOS version - 4.2.1
Baseband - 05.15.04
There don't seem to be any references to this baseband anyone got any ideas?

hey guys, im in serious need of help. i upgraded my iphone 3gs to ios 4.3.1 and the jailbroke it using a tutorial on the iclarified website. everything was running smoothly until i went to unlock it from the current provider but it wouldnt let me because it had baseband 5.16.2
i am absolutely lost and ive been reading up on blogs which say that now its useless and i cat do anythin with it...
if you upgrade 4.3.1 using the official ipsw then you baseband will be upgrade as well so until this point you can't unlock using ultrasn0w coz it does not support new baseband
dev team is not being paid by apple. - April 11, 2011 at 9:31pm
http://cutyoursim.com/.......hummmmm $170??? someone is making a profit from other people... AND... using what? a calculator??? made by??? c'mon... this is crack, I said the Dev team is being paid by apple, sorry, they are being paid by other people... because if they comes put with a solution... then this people will lose money, unless the devteam is behind this...
Depending on your UK network, you may be able to pay them to unlock it for you - talk to them. If not, then all you can do is save your SHSH for the current jailbreakable FW (4.3.1) with Tiny Umbrella and wait for the unlock. There is no current unlock available for 03.10.01, and no ETA.
I have iPhone 4 with 4.2.1 and baseband 2.10. I know I can't unlcok yet even I upgrade to 4.3.1. My questions is, if I use pwntool to upgrade to 4.3.1 and keep baseband on 2.10. If I still install Unltra sn0w, 1.2.1. Would that take the 1 signal bar issue away? Thanks if someone can help...
There is absolutely no point for you to install UltraSn0w if you're on that baseband. Unless you really, really need to go to 4.3.1 for some reason, I would just stay put on your current firmware and wait for the unlock. Save your SHSH for 4.3.1, though!
Ok, so there seems to be an issue with ultrasn0w 1.2.1 and baseband 1.59.00. The signal bars are working fine, but Visual VM and MMS no longer work.
More reports here: http://forums.macrumors.com/showthread.php?t=1134161
I have disabled ultrasn0w and both Visual VM and MMS are working, but of course the signal bar issue is back.
Can anyone here confirm or have a fix?
Ok, after reinstalling and powering off and back on, both VVM and MMS are working....
Maybe something that happens over time or after further reboots, I'll keep an eye to see if it happens again
and as I said... The dev team is being plaid by apple, or you can purchase a factory unlock, Verizon or, AT&T, that is it that are the options, because the gevey does not work in all the countries and provide full support...what I can say is that....DEV TEAM IS SOLD TO THE BEST PAYER!!!
Will this upgrade to 4.3.1 and unlock help those with iPhone 3GS using iPad baseband (06.15.00) to fix the GPS problems?
My GPS works, but it does not locate me with enough precision to be useful.
Its is locating me with an error of hundreds of meters, what makes impossible to use from routes.
It has been working this way since I upgraded to 4.2.1 and iPad baseband for unlock (06.15.00).
Anyway thanks to the dev team for keeping up...
