How great is this? A British mountain climber and guide, none other than Kenton Cool, has sent what it thought to be the first ever Tweet from the summit of Mount Everest. The ascent, the ninth for the mountaineer was sponsored by Samsung, who naturally supplied the Galaxy S2 used to send the record breaking message.
The Tweet read: "Everest summit no 9! 1st tweet from the top of the world thanks to a weak 3G signal & the awesome Samsung Galaxy S2 handset!"
He is not the first to use a mobile phone at the top of the world though - and the first ever phone call was made by another British mountaineer, Rod Baber in May 2007 - who was sponsored by Motorola for the record breaking attempt.
That earlier call was made possible as a upgrade to the local surface level network by China Mobile to put a base station within line of sight of the summit. Since then, more base stations have been installed in the area, especially on the Nepalese side of the mountain.
Other notable high altitude base stations can be found on the summit of Africa's tallest mountain, Mount Kilimanjaro.
