In a recent post, pod2G announced that the iPhone Dev team, Chronic Dev team and iOS hacker planetbeing had joined him to figure out a way to publ icly release his untethered jailbreak for iPhone 4S and iPad 2 that relied on a developer account.

It seems that there has been progress in developing an untethered jailbreak for iOS 5.0.1 in iPhone 4S and iPad 2. Now, Cydia's founder and developer Jay Freeman also known as saurik joined the team in creating the jailbreak.

MuscleNerd of the iPhone Dev team has just tweeted that the team's combined efforts is making progress. He tweeted, props to @saurik for major contributions to the A5 version of @pod2G's untether yesterday! (still no ETA, but moving forward)

pod2G also replied, @MuscleNerd @saurik And greetings to @planetbeing for the coding + research. Really great stuff to escape from the sandbox.

Thus, it looks like they have figured out a way around the sandboxing difficulties that pod2G had mentioned. pod2G has also tweeted that they don't plan to release the untethered jailbreak to developers for obvious reasons. He said, sorry, we can't release the A5 for the developers, the exploit used have to be kept secret. I know this is unfair.

As MuscleNerd has mentioned there is currently no ETA. However, this noted progress is good news for iPhone 4S and iPad 2 users.
