UltraSn0w 1.2.3 For iOS 4.3.3 Now Available To Download!

The iPhone Dev-Team has released UltraSn0w version 1.2.3 for the iOS 4.3.3 firmware to go along with the updated PwnageTool 4.3.3, RedSn0w 0.9.6rc15 and Sn0wBreeze 2.7. If you’re interested in unlocking your iPhone on iOS 4.3.3 you can do so by downloading this updated version of UltraSn0w through Cydia. It’s important to note that no new basebands are supported in this update. This, once again, is simply a compatibility update and nothing more.

From the iPhone Dev-Team’s blog:

2. ultrasn0w has been updated to v1.2.3 to be compatible with iOS 4.3.3 and earlier (the ultrasn0w update does not include any new baseband support!). Please reboot your iPhone using the normal “slide to power off” swipe after installing ultrasn0w 1.2.3.

For those of you new to unlocking, UltraSn0w 1.2.3 supports the following baseband versions:

  • 01.59.00
  • 04.26.08
  • 05.11.07
  • 05.12.01
  • 05.13.04
  • 06.15.00

If you do not have one of the baseband versions specified above, then you cannot unlock your iPhone. If you do have one of the baseband versions specified above, however, you can head on over to Cydia and download/install UltraSn0w 1.2.3 and you will have an unlocked iPhone.

    I read that ultrasn0w 1.2.2 drained the battery. Is this now fixed in ultrasn0w 1.2.3?

    I jailbreaked my 3gs using redsnow to 4.3.3. also updated baseband to 06.15.00 using redsnow.
    Now the problem is when i goto cydia on my iphone, it doesn’t opens up. when i touch the cydia icon, the cydia screen opens for a sec or less and then it goes away.
