Following the earlier information that Samsung will "unpack" and announce something "big" in Barcelona later this month, as promised Samsung put the first preview teaser on its unpack site. It's actually a 30 seconds YouTube video showing, or better hiding, the so called "Next Galaxy S". At this point we can only speculate what it is but in terms of the size it's clear that it will be a mobile phone - most likely the Samsung Galaxy S 2 - not a tablet, even if it's also expected that Samsung will also unveil the Samsung Galaxy Tab 2.
If you can't attend this year's Mobile World Congress, we'll be on-site as well as Samsung will stream the unpack event, also known as its press conference, live on 13 February at 19:00 CET.
