Jailbreaks are not yet made available for users with iPhone 4S and iPad 2 models, which are powered by Apple's more powerful A5 processor. Though Pod2g and MuscleNerd have updated through Twitter on the progress made, there is still no exact date on which it will be available.

MuscleNerd has tweeted, props to @saurik for major contributions to the A5 version of @pod2g's untether yesterday! (still no ETA, but moving forward). Saurik is responsible for developing Cydia, which is a software application for iOS that enables a user to find and install software packages (including apps, interface customizations, and system extensions) on a jailbroken iPhone, iPod Touch or iPad.

This is the second time when Saurik has helped @Pod2G to make untethered JailBreak possible. Though the exploits were found by @Pod2G himself after months of work and experiments. At first, Saurik had helped Pod2G when there were cache issues while porting untethered JailBreak to A5 devices for the stability.

Meanwhile Pod2g tweeted, And greetings to @planetbeing for the coding + research. Really great stuff to escape from the sandbox. A major obstacle for having an untethered jailbreak for A5 devices was the Apple sand, a security mechanism meant for separating running programs. It is frequently used to execute untested codes and programs from unverified third-parties.

Previously, Pod2G gave an ETA on Twitter according to which untethered JailBreak for iPhone 4S and iPad 2 would be released in a week. It has already passed and there is still no indication of the highly anticipated jailbreak.
