如下是为所有运行于 GSM 网络的 iPhone 3G 和 3GS 通过 UltraSn0w 进行解锁的方法。

按照如下指导进行解锁之前,你的 iPhone 必须已经做过「越狱」(jailbreak),并且你的 iPhone 基带(baseband,即调制解调器固件)版本必须是 04.26.08。这意味着,你的 iPhone 目前已运行在 iPhone OS 3.0 版本上,并且此前曾使用 PwageTool 或者 RedSn0w 做过越狱。

欲获知你的 iPhone 固件及调制解调器固件(基带)版本号,可以去这里看看。如果你的 iPhone 基带版本号不是 04.26.08,你则需要在对其解锁前,首先参看下列其中一个教程:Mac 教程 / Windows 教程

如果你的 iPhone 运行于 T-Mobile 网络之上,记住要在动手前先关闭 3G 服务。

在主屏幕中点击运行 Cydia Installer

I finally made it on an iPhone 3G, 4.2.1, 5.15.04!!! Thanx for the tutorials, although they contain only bits of information, and if you get stuck anywhere you'll have to google further. To succeed, I used redsn0w v. 0.9.14b2, not the latest one (the latest one will give you faulty baseband after downgrade with no wi-fi, bluetooth or IMEI, and you will have to start all over again). After upgrading the baseband to 6.15.00, I got stuck on apple logo (bricked phone). To bypass this, you need to download, and Select IPSW iOS 4.1 (not 4.2.1), and use "Just boot" option. After the phone boots, it will be buggy (the screen), but it will become alive again. Check if the baseband is 6.15.00. If yes, proceed to Jailbreak in redsn0w (this time using 4.2.1 IPSW), and tick the boxes Install Cydia, and Downgrade baseband. After it is done, you will have an iPhone with baseband 5.13.04, which you can unlock with ultrasn0w, but (most probably) with "No service" bug. To resolve this, follow the tutorial concerning this matter, and voila! iPhone unlocked. This procedure felt like walking through thick bushes...

iPhone 3GS Version: 6.1.6 Modem firmware: 06.15 Install cydia ultrasn0w install finish... No service... How? Please help?
nomad - March 7, 2014 at 9:13pm
uninstall ultrasn0w, use redsn0w to downgrade from ipad baseband, that should bring you to baseband 5.13.0 or something like that, then install ultrasn0w again, good luck
nomad - March 8, 2014 at 11:13pm
correction : that should bring you to baseband 5.13.04 , i just tried it today

That worked for me on 3GS 6.1.6. From the beginning if I remember correctly, 1. redsn0w: uncheck Cydia and everything else, check upgrade to ipad baseband 2. Repeat redsn0w, this time with: check Cydia, check downgrade baseband. Now you have tethered boot 3. In redsn0w: Just boot 3. From Cydia, install p0sixspwn. This makes it untethered boot. 4. From Cydia, add the ultrasn0w repository and then install ultrasn0w. Voila! Service! For me the key step was to start over, then upgrade baseband first and then downgrade baseband. Finally recognized T-mobile sim.

Just did the jailbreak on my 3G using the iClarified instructions, and included the iPad baseband when I did it. Worked fine, now jailbroken, and shows 06.15.00... but, when I try to run the above, when I click to install Ultrasn0w, I get "the requested modifications cannot be applied due to...' :S

my iphone 4 basband is 4.12 how to downgrade to 4.10 ? 1.59 ?
daoshi - January 27, 2014 at 6:10am
I have an iPhone 4s with iOS 7.0.4, I cannot down grade to 6.x or 5.x. After I tried the steps suggested, it comes with a message "SIM Not Valid". Anyone suggestion, ot it just doesn't work for 7.0.4? Thanks. Joseph

Hi all! I've just jailbreaked my iphone and now tried to unlock it because I changed carrier... now, it keeps searching for the carrier and I cannot make any calls... any suggestion? I'm a bit "fresh" on this kind of matters. Thanks all

Thanks you so much..

Worked at last. Thanks guys. Downgrading my baseband from 6.15 to 5.13.04 did the trick. I have 3Gs and updated it to 6.1.3. with iTunes, JB with redsnow, install Cydia, Ultrasnow, then p0sixspwn for untethered JB. Found everything OK, except it was still SIM locked. Did the baseband downgrade with Redsnow and right away I could call out. Thanks again.
Gaurav - January 11, 2014 at 8:44am
Thanks Iclarified. I got my phone unlocked. Now can i update my phone to ios 6.1.3 (currently on 4.1.1) without getting my phone locked again ?
