Unlock iPhone 4 & 3GS iOS on 5.0.1 with Ultrasn0w 1.2.5
Ultrasn0w 1.2.5 was just pushed out today to fix ultrasn0w compatibility issues with iOS 5.0.1. Once you have jailbroken your iPhone 3GS or iPhone 4, follow the instructions below.
iPhone 3GS with baseband 5.14.02, 5.15.05, 5.16.02 and 5.16.05 cannot be unlocked with ultrasn0w. It needs to be updated to 6.15.00 (iPad’s baseband) first – there is a risk that your GPS may stop working. See tutorials here.
iPhone 4 with baseband 2.10.04, 3.10.01, 4.10.01 and 4.11.08 are not supported.
Note: Only the following baseband versions are supported:
- 1.59.00 (iPhone 4)
- 4.26.08, 5.11.07, 5.12.01, 5.13.04 and 6.15.00 (iPhone 3GS)
Carrier Unlock Steps:
Before you start, remove the SIM card from your iPhone.
Step 1: Launch Cydia from the springboard.
Step 2: Tap on Manage.
Step 3: Search for ultrasn0w on Packages in Cydia. If you cannot find it, add new Sources by typing: repo666.ultrasn0w.com.
Step 4: A new ultrasnow package will be installed. Once done, go to Packages and look for ultrasnow. Tap and install it. During installation, you will see a black screen with running command lines.
Step 5: Reboot your iPhone and insert your SIM card. Toggle the Airplane mode to ON and then OFF. Your iPhone will search and register to your mobile phone network. Please be patient, sometimes it may take up to 3 minutes.
If the jailbreak is tethered, remember to use redsn0w or iBooty to boot it. Otherwise it will stuck on the Apple logo.
Congratulations! You have successfully unlocked your iPhone. If you encounter any issue, please leave your comments below.

I got a friends done last night. Ultrasn0w didnt install in the usual way. Sorry but Im at work so cant check Cydia at the mo' but basically I had to use Search after I had downloaded it as it was 'hidden' I then installed it once the app appeared. Dont forget
Im stuck now as the Iphone can pick up my Virgin mobile Sim but not my friends Orange sim. Hes on Orange 11.0 if that means anything to anyone
u need to reboot
Same here…like above(sherman)
I'm in the same position. I have installed everything appropriately, I have a 3GS, iOS 5.0.1 with 6.15.00, and it is not unlocked. I used Redsn0w and didn't changed the bandwidth because I already had a 6.15.00 bandwidth, could that have been the issue?
i have IPhone 3GS, IOS 5.0.1 with 6.15.00 baseband, and i installed ultrasn0w from cydia and changed it to Ipad baseband but still showing 'No Service' help me please..

Somebody know when the official ultrasnow unlock for bb 05.16.05 will be out? I need my mms. Thanks
I have the same issue, seems as everything installed correctly, but didn't get any signals at all
iPhone 3GS? Reflash iPad baseband if you already have it
where can I find the info to "reflash iPad baseband?" …because I have no idea
use redsn0w, jailbreak, install iPad baseband
Two solutions, one let the battery run empty and leave it like that for 3 days !! then put it on the charger. This worked for me as with the total empty battery it resets itself and did't hang at the apple logo no more.
second just install the standard ipsw without the baseband using snowbreeze ( windows only ) and then custom restore with itunes
good luck
