Yesterday we told you that Vodafone Australia announced Nexus S owners that the highly anticipated Android 4.1 Jelly Bean update for the second-generation Nexus smartphone will be rolled out today.

Well, it turns out that Vodafone is not ready to release the update, not that we’re surprised to see an Android upgrade postponed by a carrier. At the same time, we’ll point out the obvious fact about the handset: we’re looking at a Nexus device that should have no problem running the new OS, and should receive new updates a lot faster than other devices. However, that doesn’t seem to be the case, at least with the Australian Nexus S version.

Apparently the Nexus S Jelly Bean update does not meet regulatory requirements regarding emergency calls. Here’s what Vodafone posted on its blog, without providing a detailed explanation:

We’ve just been advised that due to a software issue, the roll-out the of Android 4.1 Jelly Bean update to Vodafone Australia customers has been delayed.

It’s been advised the software currently does not meet all the Australian regulatory requirements related to emergency calls.

Naturally, we don’t have a different release date for you at this time, so you’re back to waiting. Hopefully, it won’t be long now.
