A renowned British climber has taken Twitter to a new high, firing off the first tweet from the peak of world's tallest mountain.

"Everest summit no 9! 1st tweet from the top of the world thanks to a weak 3G signal & the awesome Samsung Galaxy S2 handset!" the mountaineer said in a tweet sent Thursday.
Nepal telecom carrier Ncell installed a mobile signal receiver at the base of Everest late last year, but it had been unclear whether its range extended to the peak.
A blog post at Cool's website dream-guides.com proclaimed the Samsung Everest climb a success and promised more details as Cool made his way back down.
