Updates from Google and Microsoft for two of Samsung’s most popular devices, the Google Nexus S and the Samsung Omnia, are currently rolling out though not everything is going as planned for everyone involved.

A tweet posted by Google’s Nexus Twitter account indicates that Google Android “Gingerbread” version 2.3.3 would begin rolling out with a window of “a few weeks” to get all Nexus S and Nexus One handsets updated. The update includes mainly bug fixes with no new major features being added.

Microsoft began rolling out an update of their own for the Samsung Omnia, one of the first Windows Phone 7 smartphones to hit the market last year, but problems reported by users following the update are giving others pause. The upgrade is a small one intended as a bridge to a bigger update expected next month that will include copy/paste functionality among other goodies, but Microsoft is backtracking at this point after reports of various problems. Microsoft says that they are aware of the issue and will have a fixed update prepared as soon as possible; Omnia owners may want to hit the “ignore” button on that update until then.
