i have an iphone 3G os 3.0
@ricanvent
Try re-installing UltraSn0w with your SIM card inserted.
If you’re using T-Mobiles:
T-Mobile in the USA doesn’t use the 3G frequencies that the iPhones support, so turn off 3G in Settings->General->Network. (Some T-Mobile territories gracefully hand down to Edge mode, but most do not).
I’m with AT&T. Should i do something different?
ok, reinstallation worked like a charm…. thanks a lot!!!!
first time I did it was cool, somthing go wrong so I started doing it agin after few days:
ultrasn0w is diffrent from the firse one I used this one is:
iphone Dev Team’s 3G and 3GS software
the old one was;
an iphone 3G soft unlock application for 3.0
I am using the same resourc which is:
http://repo666.ultrasn0w.com
and getting an error (size mismatch)
any idea

@ 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 :D. You are awesome thx so much !
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
the confirm button does not come once the source is installed it say due to conflicts that cannot be found
i’ve recently upgraded my iphone 3G from 2.2.1 to custom activated 3.2.1 fw successfully.. I tried to unlock by ultrasn0w through cydia. ultrasn0w got installed but i get ‘No Service’, unable to call… able to connect to WLAN….
reset network settings… reboot 🙂
I appreciate your reply very much..
Did a couple of times, no luck. Redone the whole process twice, no luck… Any problem with these details
Version 3.1.2(7D11)
Carrier Carrier 5.0
Modem Firmware 02.28.00 ??
Many Thanks
Finally worked when I used Fuzzyband Downgrader.. Worked like charm.. Thanks for all your help guys..
try this:
http://www.iphoneheat.com/2009/10/download-iphone-os-3-1-2-custom-firmware-ipsw-files-for-iphone-3gs-3g-2g/
and then unlock using UltraSn0w
Thank you for your detailed explanations iPhoneHeat. I just did Jailbreak iPhone 3GS, 3G OS 3.1.2 with PwnageTool 3.1.4 (Mac). After that to unlock I used ultraSn0w but couldnt get it workin. My modem firmware 05.11.07
What do I do to fix it?
you should be using BlackSn0w… checkout http://www.iphoneheat.com/2009/11/how-to-unlock-iphone-3gs-3g-os-3-1-2-baseband-05-11-07-using-blacksn0w/
Cydia isn’t working for me, it keeps giving me error messages when downloading. (http://apt.saurik.com/ POSIX: Operation timed out) What can I do? I am stuck with a phone that isn’t a phone.
okay i did everything correctly..
i put in my sim card and where the network is supposed to be displayed, it says “searching…” what do i do?
Your baseband?
I have unlock my iPhone 3G OS 3.0 BB 4.26 with ultrasnow. I can see that my iphone recognizes the network T-Mobile but I can’t make any calls nor received any calls though I have a full bar of signal. Any suggestions? Thanx.
reset network settings
THANK YOU! Ultrasn0w worked flawlessly!
OK. Here’s what had happened.
3G running 3.0.1 Jailbroken with Pwanage and Unlocked with Ultrasn0w: Cydia became unusable. A few months later the iPhone started running very slowly.
Restored in iTunes.. ipsw 3.0.1 A700
Launched Pwanage 3.0 to “cook” the ipsw. Pwanage couldn’t recognize the ipsw file. I had to “cook” ipsw 3.0.7.. WTF?
Anyways I was able to JB/Unlock, but now it’s running 3.0 instead of 3.0.1.
Anyone else experiencing this?
Thnx,
AM
