Few days back, MuscleNerd – the most vocal member of the iPhone Dev team revealed that they’re working on a promising unlocking solution for iPhone 4S.

MuscleNerd has just posted an update on the progress on Twitter.

iPhone4S baseband bootrom now dumped :)

Here’s a tiny snippet: http://twitpic.com/7mg5hp …but we’ll be digging into the rest of it too! :)

iPhone 4S teardown had revealed that it comes with Qualcomm MDM6610 chipset, which is confirmed in the tiny snippet below:

The baseband bootrom (called “SecureROM” by Apple) is the first code that runs on the baseband processor in the internal ROM. It is read-only. It looks like Dev team has found an bootrom exploit, which is a huge achievement as Apple won’t be able to fix it without a hardware revision.

The last time Apple had to do it was with iPhone 3GS. Back in October 2009, three months after iPhone 3GS was launched, Apple started shipping iPhone 3GS with new bootrom to prevent jailbreaking, which is the reason we keep talking about iPhone 3GS with old bootrom.

Since users will first need to jailbreak the iPhone to unlock it, it looks like Dev team is gearing up to launch a jailbreak and unlock for iPhone 4S. Let’s hope that while the unlock will only be available for iPhone 4S users, it will at least support an untethered jailbreak for iPhone 4 and iPhone 3GS along with the iPads and iPod touches.

Dev team haven’t provided an ETA on when it will be released but as always, we’ll keep you posted if there are any further updates, so stay tuned here at The iPhone Nerd or join our Facebook Fan page .
