With the release of the final commercial version of iOS 5, you can see that the jailbreak community is currently on their feet in order to make their jailbreak tools, tweak and apps be compatible with Apple's most advanced mobile operating system. This is definitely true with the iPhone Dev Team, the folks we all know responsible for the popular Redsn0w tool. And yet again, the iPhone Dev Team updated Redsn0w which makes the tool's jailbreak speed even more faster.
It was only a couple of days ago that the Dev Team released Redsn0w 0.9.9b6 which fixes the location services bug found in the iPhone 3GS supporting a certain baseband. And now, Redsn0w 0.9.9b7 is available for download for both Windows and Mac. After the Dev Team received several feedbacks from jailbreakers on Reddit, they have decided to update Redsn0w which now allows for a faster jailbreak. How? Redsn0w users will now be given an option of no longer stashing applications by default when running the tool. Because of this, the iPhone Dev Team managed to cut down the overall time to perform the jailbreak from 210 seconds to 80 seconds. That is a 60% improvement in speed.
Be advised though that while the time was significantly reduced during the jailbreak process, launching Cydia for the first time means that it will stash the applications, making up for the reduced time during the initial jailbreak. Basically, this gives users an option whether they prefer either Redsn0w or Cydia to stash the applications. Just go to Extras > Preferences > and tick / untick the Move applications option depending on your preferences.
From the iPhone Dev Team Blog:
Update #15: After some feedback on reddit, we’ve decided to make the initial jailbreak as quick as possible by no longer “stashing” the applications by default during the redsn0w run. This reduces the time to actually perform the jailbreak from 210 seconds to 80 seconds (60 percent!). However, you make up for much of that the first time you launch Cydia, which will then want to stash the applications. You can choose whether you want redsn0w or Cydia to stash in the Preferences pane.
It is worth noting that the Windows version of Redsn0w 0.9.9b7 unfortunately still does NOT support the creation of custom IPSWs. And yes, this is still a tethered jailbreak solution. This means that when your iPhone, iPad or iPod touch gets shut down or reboots, you will need to connect it to a computer and run it over Redsn0w to boot it into tethered mode. So if you are expecting a tethered jailbreak at this time, we are sorry to disappoint.
Redsn0w is one of the most popular jailbreak tool around and known for its overall reliability and stability and also for its timely updates. With the recent versions of Redsn0w, pointing the program to the IPSW of the firmware you are jailbreaking to is no longer necessary. This is because Redsn0w automatically fetches the necessary components from Apple in order to jailbreak the device. A very useful feature since you won't be needing to keep those bulky iOS IPSW files. In addition to that, Redsn0w can now create custom IPSW which enables users to preserve their unlockable baseband, although as of now this feature is available on Mac versions of the tool only.
