Kenton Cool, a British mountaineer, became the first person to send a Twitter message from the top of Mount Everest on Thursday.
Everest summit no 9! 1st tweet from the top of the world thanks to a weak 3G signal & the awesome Samsung Galaxy S2 handset! @samsunguk
Ncell, a mobile carrier in Nepal, installed a 3G network base station at the base of Mount Everest in October 2010.
