Proving (as usual) that it's not too big for a little tit-for-tat with its crosstown rival, LG showed its own concept solar phone at MWC this week to match up with Samsung's Blue Earth. The prototype LG handset doesn't have a name -- takes a whole team of high-priced consultants to christen a product like that, we'd wager -- but we do know that the slider can eke 3 minutes' worth of life out of a 10-minute charge in natural light. The thing looks like it was thrown together in a week, but hey, as long as it works, we know LG can take care of the design side of things by the time production rolls around.
