iPSW Firmware

Have you read the news or got any update on your iPhone/iTunes about Apple’s iOS 5.1.1 Build 9B208 update for iPhone 4 GSM? The very first iOS 5.1.1 version contained the build number 9B206 but today’s update contains a new build 9B208. Most users won’t find this update on their device or through iTunes, but Apple has actually released it and is rolling it out slowly to other countries and carriers.

We don’t have any word from inside Apple what’s new in this new build. No official changelog is provided so far. But one thing is very clear that it invalidates the iOS 5.1.1 untether payload. It doesn’t mean the untethered jailbreak has been patched in this minor update, but you can’t get the untether jailbreak on your iPhone 4 GSM after installing this update until Chronic Dev Team pushes a new Absinthe 2.0 containing fixes for 9B208.

iH8sn0w also conveys the same message through his blog post:

iPhone 4 (GSM) & Apple’s 5.1.1/9B208 Update:
This evening, Apple appears to have (surprisingly) released 5.1.1/9B208 for the iPhone 4 (GSM) exclusively. Although there isn’t much of a difference it was enough to make the 9B206 untether payload for the iPhone 4 (GSM) invalidate on 9B208. Until pod2g/planetbeing build an untether payload for this build, 9B208 support is not included. A small update will be pushed whenever this occurs. This doesn’t mean the untether was patched though.

If you wan’t to get the untethered jailbreak, don’t install this update. And if you have accidentally updated your iPhone 4 (GSM), you can restore the fresh iOS 5.1.1 Build 9B206. But please hurry up to do so since the signing window is still open.
