@ ski 13
UltraSn0w even unlocks OS 3.1.2 but only if your MOdem firmwares is 04.26 or lower. It can’t unlock 05.11
if I would to restore a clean 3.1 or 3.0.1 fireware will it still keep the 5.11 modern or will it down grade it. If at all possible I have a 3.1.2 fireware and a 5.11 modern how can I get it to work with ultrasnow.
Thanks,
Sorry you can’t downgrade baseband by downgrading firmware..
If you have Cydia on ur iPhone try 3G Fuzzyband from cydia it will tell you if your baseband is downgradable.
Hi guys i´ve just finished jailbreaking and unlocking and it seems it works

Hello, I’ve just followed the whole process on my iphone 3G and after everything, it’s not recognising any sim card. Can you please help?
Your OS? Baseband?
nice … it works perfectly on my 4.28.06 … but the unlocking part was quick and dirty!
Hi, I followed the instructions above and just installed Ultrasnow from Cydia on the 3.1.2(7d11) firmware. My modem firmware is 2.28.00. I’ve just restarted the phone, but it says “no service”. It’s unable to recognize my sim card. I followed the directions with the 3g off. Can you help me?
I just saw a message in Cydia that says,”If you upgrade to 3.1.2 without using Pwnagetool to do so you will not be able to unlock your phone at this time, and maybe forever after.”
I did the custom restore method of using the custom .ipsw files in itunes 9. Is that the problem?
He mentioned that if you do WITHOUT using PwnageTool..
Custom Firmwares are created with PwnageTool..
because it’s for MAC only so I have created custom firmwares for Windows users:
http://www.iphoneheat.com/2009/10/download-iphone-os-3-1-2-custom-firmware-ipsw-files-for-iphone-3gs-3g-2g
I’m not sure what you mean exactly sorry. I dled the custom firmwares provided on the site. After the jailbreak, I went on to unlock the phone w/ Ultrasnow, but it doesn’t recognize my T mobile service.
you can use Fuzzyband Downgrader to upgrade your baseband to 4.26 then reinstall Ultrasnow. it should work like magic.
try resetting carrier/network setting..
turn OFF/ON airplane mode..
or
reinstall UltraSn0w
I’ve tried reinstalling Ultrasnow 3 times on separate occasions. Nothing. The airplane mode and resetting carrier settings doesn’t work neither.
On the settings menu, the carrier option disappears, going in and out. I don’t know if that helps with much because either way, it doesn’t detect a service.
Did you disabled 3G before installing UNltraSn0w?
so it now and reinstall..
and also try turning OFF and ON the AirPlane Mode.
I justed broke my iphone 3g out of ATT Correctional Facilities and im feeling like a new man, the unlocking was seemless. BYE BYE ATT
