It's nothing but wide open space on the top of Mount Everest, right? I'm assuming, since I've never been there. But chances are you wouldn't think twice about pulling out your cell phone to let your loved ones know you made it! That is, if you could get a signal up there.

Apparently it's not that easy.  When a British mountaineer got to the summit over the weekend, he pulled out his smartphone and gave the BBC a video billed as "the world's first live video call ... from the rooftop of the world." Now Nepal tourism officials are upset because he didn't clear it beforehand. The climber was one of nearly 150 people who reached the summit on Sunday alone. One critic thinks all these inexperienced hikers are making a mess of the mountain, though there have been some nice milestones of late—along with a sherpa fight.
