If you thought that simply because you were buying a Galaxy Nexus phone you will be ready for a true Google Experience, guess again! There are a couple of different versions . Google’s own build for the Galaxy Nexus is named “yakju”, alternative builds yakjusc, yakjuxw and yakjuux (so far) are from Samsung, not Google. While the experience is mostly the same between the different versions, only Google’s yakju build is guaranteed to ge updates as they happen. Samsung will presumably distribute the updates to their modified build but at a later time.
