Apple has seeded a new beta of iOS 6.1 to developers for the iPhone, iPad, and iPod touch. It was widely expected that Apple would release either a GM or a fifth beta this weekend since the current fourth beta for 6.1 expires on Monday.

As we noted in a previous post, this is only the second time that Apple has released a fifth build for a non-major iOS update. Developers can head over to the development portal now to download the latest beta release.

It’s a bit weird that Apple released the beta on a Saturday evening, but as mentioned, it’s a bit more odd that this isn’t a golden master release like we expected.

This proves to be disappointing, because it means it pushes out the window for an iOS 6.1 jailbreak release a bit further. It’s widely expected that the team working on the iOS 6.1 and iPhone 5 untethered jailbreak won’t budge before iOS 6.1 is public.
