Jailbreak “Dream Team” has finally squashed the issues in Sandbox, which was considered to be a major blockade for untethering iPhone 4S and iPad 2 jailbreak. iPhone Dev team’s Musclenerd praised Saurik’s effort in coding the sandbox on top of pod2g’s untethered exploit that will now lead to perfect stable A5 jailbreak.
The recent tweets from pod2g and Musclenerd suggests that they have successfully injected the untethered files to the iPhone 4S without requiring a developer account. This is indeed a big step forward and if this is true then the team could be in process of packaging the exploit into both redsn0w and greenpois0n tool. Before releasing A5 jailbreak, the team will likely test its compatibility with popular cydia apps as well like MobileSubstrate.
pod2g has denied releasing the A5 jailbreak for the developers, since he intend to keep the exploit secret, which is fair.
On ETA upfront, we would advise everyone (whoever seeks for iPhone 4S or iPad 2 jailbreak) to stay calm. The team is hard at work and they will announce A 5 jailbreak as soon as they can. We will update you about its release along with the tutorial guides, just follow @JAlLBREAKS on twitter.
