Ultrasn0w Releases by Dev-Team for ios5
ultrasn0w 1.2.4 released for iOS5
pre-QUALifier
We’ve updated ultrasn0w to be compatible with iOS5, which came out a few days ago. While ultrasn0w 1.2.4 doesn’t add support for any new basebands, the update is required for any ultrasn0w unlockers trying out iOS5 (it remains backwards compatible though, so you should be able to use it no matter what firmware you have).
The supported basebands for the iPhone 3G and 3GS are 04.26.08, 05.11.07, 05.12.01, 05.13.04, and 06.15.00. The baseband supported for the iPhone4 is 01.59.00.
You can determine your baseband by following these instructions.
Settings>General>About>(scroll down).
Remember, the only way to get to iOS5 while preserving your ultrasn0w-compatible baseband is by using a custom IPSW.
The majority of people who use ultrasn0w at iOS5 right now will probably be those with old-bootrom iPhone3GS devices, since they already have an untethered jailbreak via redsn0w. For everyone else, the iOS5 jailbreak is currently tethered and you need to “Just boot” tethered with redsn0w every time your phone reboots. That’s not always easy to do if your phone reboots while away from home!
Note: there’s a special “trick” that iPhone3GS owners with baseband 06.15 need for iOS5. During the new setup screens you see when you start iOS5 for the first time, you’ll be asked about Location Services. Be sure to select “Disable Location Services” when asked! Later on in the setup, you’ll have the chance to turn on Location Services again when asked if you want to use “Find my iPhone”. It’s fine to turn it back on at that point, if that’s your desire (or you can always go in and enable it in Settings.app).
Also, some iPhone3GS users with the 06.15 baseband may have tried to install iOS5 using a stock IPSW (even though you should never ever try to use a stock IPSW if you’re an ultrasn0w unlocker). If you did try this, your baseband is probably in an inconsistent state, and you’ll need to reflash the 06.15 baseband again (using redsn0w). Be very careful if you use redsn0w to reflash the iPad baseband — don’t interrupt the process1 And please avoid using stock IPSWs in the future Unlockers should never go near stock IPSWs.
If you need to use redsn0w for any of the above tasks, please make sure it’s version 0.9.9b4 or higher, which is available here.
GUIDE HOW TO INSTALL UltraSn0w
Run Cydia or Icy
Please add the repo repo666.ultrasn0w.com to Cydia or Icy. That last “o” is actually the number zero “0”! If you use the letter “o” you’ll get an error.
Search for ‘ultrasn0w’ in cydia or icy and install ultrasn0w
Reboot your iDevice
T-Mobile USA users should disable 3G before using ultrasn0w
Enjoy
