In the past 24 hours iOS 6.1 beta 3 has been made available for developers to download, along with notes which tell about a few changes that have been made.
iOS 6.1 Beta 3 jailbreak available; iPhone 5 untethered jailbreak still not ready
This includes making it easier for app creators to include Apple Maps in their apps. Apple have included new mapping APIs, but other than this change, the rest are considered minor, and are a far cry from what we have seen in the past with beta updates.
Now there is also a video which shows users how they can jailbreak the iPhone 4S when running iOS 6.1 beta 3, however for the time being there is no jailbreak for the iPhone 5.
Beta 2 went live 21 days ago for developers and both beta updates bring about bug fixes and improvements. Developers who want to install will need Xcode 4.6 Developer Preview 3, however iOS 6.1. Beta 3 could also be installed over the air, providing you already have the previous update. Not much has changed and therefore a changelog has not been provided here, so we have to hope that the next beta will have more to offer.
Those who want to jailbreak iOS 6.1 beta 3 can check out the video below which shows how this is possible on the iPhone 4. A video was also posted yesterday which shows how far along developers are when it comes to iOS 6 untethered jailbreak. It also shows the importance of developers being able to dump the bootROM as this would stop updates from patching a jailbreak on the latest iPhone, the iPhone 5.
