The iPhone Dev-Team has released an update to their UltraSn0w unlock bringing support for iOS 5. Remember that NO new basebands are supported in this release. It only adds support for iOS 5 with old basebands.
Here is the list of supported basebands:
If have one of the above baseband version and need unlock you can upgrade to iOS 5 without updating your baseband using .
Ultrasn0w 1.2.4 is available in Cydia.
The iPhone Dev-Team has released RedSn0w 0.9.9b5 – an official tethered jailbreak for iOS 5. Users don’t have to point to downloaded iOS 5 ipws any more. Just run and jailbreak.
Currently only the Mac version has been made available. Windows version is coming soon. However Windows users can still jailbreak iOS 5 with Redsn0w 0.9.9.b4, – just go to “Extras” -> “Select IPWS” and select your iOS 5 ipsw file (can download ).
Good news for users who need carrier unlock (ultrasn0w or Gevey Sim). With RedSn0w 0.9.9b5 you can update to iOS 5 and preserve the baseband (modem) version for unlock:
The new “Custom IPSW” button on the Extras screen will create a custom IPSW without the baseband update for 4.3.3 or 5.0gm (iPhone3GS and iPhone4 only, for now). Remember not to accidentally restore to the stock IPSW after you create the custom one! The custom one begins with NO_BB_ (for “no baseband”).
You must enter “Pwned DFU” mode before trying to use the NO_BB_ IPSW with iTunes (and your hosts file cannot be pointing to Cydia’s servers due to the new blob nonce mechanism they’re using in iOS5).
We will update our step-by-step tutorials soon.
You can download RedSn0w 0.9.9b5 (Mac) and RedSn0w 0.9.9b4 (Windows) .
PS: RedSn0w 0.9.9 is a bit different from 0.9.8 version. You can learn more about other new redsn0w 0.9.9 features .
