Note to self: next year, make sure to attend Mobile World Congress. Not only is the show in Barcelona, but several interesting new phones have been unveiled there -- and the stage has been highlighted by a bevy of tech CEOs.

One high-level takeaway: from the LG Optimus 3D to the Sony Experia, the new generation of smartphone competitors are getting farther away from the iPhone clones that seem to be all over the market now. I'm curious to see how they stand up in the face of what may be major revamps of the iPhone this year.

While we wait to find out, take a look at some photos from Mobile World Congress.
