Vodafone Australia updated customers regarding the issue on its company blog.
The company's post didn't go into details as far as when the update process will resume. Vodafone Australia only mentioned that customers should continue to check the company blog for further news.
Prior to the release of the Samsung Galaxy Nexus, the Samsung Nexus S was Google's developer phone. As a pure Android phone, sans any UI layer such as Samsung's normal TouchWiz, it is expected that various versions of the phone will receive Jelly Bean soon.
The addition of UI customizations such as HTC Sense, TouchWiz, and Blur have been blamed for the update lags between the release of a new version of Android and updates to various handsets. Apple made fun of this when it introduced iOS 6, noting at the time that while Android 4.0 was released at roughly the same time as iOS 5, only about seven percent of Android devices were sporting it.
The same lengthy upgrade timeframe is expected for Jelly Bean.
