Jailbreak iOS 5 on iPhone 4, 3GS, iPad and iPod Touch using Redsn0w 0.9.9b5 is now available and for those of you who wanted to upgrade to the fresh-out-of-the-oven iOS 5, but not lose your jailbroken app goodness, as well as all of those hacks and tweaks you've fallen in love with, today is your day.
There were rumors that iOS 5 would stop any of these types of hacked upgrades, but people still want their stolen apps and games, right? Maybe it's just tweaks and hacks to the original iOS 5 that you're after, but everyone is different. Of course, there are some jailbreak apps that just don't work with iOS's default software. SBSettings for example, bringing control of your iDevice's vital features using a simple activation method.
The iPhone Dev-Team has released a tether-jailbreak (which means you'll require it to be connected to a computer when the phone turns on, every time) which is explained below:
With today's official iOS5 release, redsn0w has been updated to 0.9.9b5 to include the public URLs for the IPSW files. This way, first-time iOS5 jailbreakers don't need to supply the IPSW file manually. It's still a tethered jailbreak on all except the old-bootrom iPhone3GS, and it doesn't apply to iPad2 or the upcoming iPhone4S.
Because the jailbreak is currently only tethered for most devices, we're not going to release a new PwnageTool yet. Instead, we've decided to build some of PwnageTool's functionality into redsn0w (since you need redsn0w to "Just boot tethered" on every power cycle anyway). 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).
Version 0.9.9b5 is available only for Mac for now, until we can do more testing on the Windows version of "Custom IPSW".
We're currently working on a normal compatibility update for existing ultrasn0w unlockers. After that we'll try to fix the iBooks issue on jailbroken iOS5.
Of course, there are things you'll need to remember:
This will not work with iPad 2, nor the iPhone 4S.
This is a tethered jailbreak, meaning that it will require you to connect the phone to a computer running Redsn0w whenever you power up the phone.
As has been the case before, by pursuing the tethered route, if and when an untethered jailbreak does surface, the chances are you'll have to restore in order to utilize it.
