Trivial? You bet! However, everything’s done for a reason in Apple-land. Not officially stated on their site but you’ll notice everything has been quietly changed to reflect the new naming scheme, for example the 3GS product page. Makes sense to me really, never did see any logic in the 3G<space>S gimmic. Of course, people will continue be confused by the ‘3G’ tag anyway, wondering if it means ‘3rd generation’ or ‘3G cellular technology’ (it’s the latter).
