Dev-Team has released UltraSn0w 1.2.4 to unlock iPhone 4, 3GS running iOS 5 firmware. This UltraSn0w update can unlock iPhone 4, iPhone 3GS on unlockable basebands running iOS 5. These are the steps to unlock iPhone 4, 3GS iOS 5 with UltraSn0w unlock.
For those who don’t know, UltraSn0w is a software unlock solution for iPhone, created by the iPhone Dev-Team, so that users can use their iPhone on any carrier other than the official ones.
ATTENTION:
UltraSn0w 1.2.4 can unlock iPhone 4 and iPhone 3GS on iOS 5 with compatible basebands only. Sadly, newer basebands aren’t supported.
Supported basebands include:
(How to: check iPhone baseband)
iPhone 4 baseband: 01.59.00
iPhone 3GS Baseband: 04.26.08, 05.11.07, 05.12.01, 05.13.04, 06.15.00 (Read the note at the bottom)
UltraSn0w unlock requires your iPhone to be jailbroken on iOS 5. RedSn0w can jailbreak iOS 5 and the good thing about new RedSn0w 0.9.9b4 or later is its ability to preserve baseband just like the PwnageTool and Sn0wbreeze does.
If you’re on any of the above mentioned basebands, follow > this guide < to Update to iOS 5 + jailbreak and preserve iPhone baseband. ***Make sure to preserve baseband*** Gevey SIM guide is also linked at the bottom.
Unfortunately, it’s still a tethered jailbreak which means you have to connect your iOS device with your PC on every reboot to boot back into the jailbreak state. Untethered iOS 5 jailbreak is expected to be released soon.
Let’s Unlock iPhone 4, iPhone 3GS iOS 5 with UltraSn0w on the compatible basebands…
How to Unlock iPhone iOS 5 with UltraSn0w
Step 1
Jailbreak your iPhone 4 or iPhone 3GS using the latest version of Redsn0w or Sn0wbreeze on iOS 5.

I upgraded iPhone 3GS (new bootrom) with IOS 5 custom IPSW preserving my BB 05.12.01, but i get no signal after installing ultrasn0w.

In many posts i read that upgrading to ipad baseband have worked but as per Dev team my BB is unlockable and i do not want to upgrade to iPad baseband.

Tried doing a just boot on Redsnow and there was no difference. Tried to remove then install Ultrasn0w and there was no difference. Tried to remove then install Ultrasn0w then just boot and STILL no difference. Tried reseting network settings and there was no difference and finally switched airplane mode on took my sim out then switched it off and put my sim back and and once again still no difference.
