The first 3G connection and the world’s highest tweet were made today from the summit of Mount Everest on Samsung’s new Galaxy S II smartphone.

British-born mountaineer Kenton Cool reached the summit in the early hours of this morning having unboxed his Galaxy S II at base camp.

When he reached the summit, he made the very first 3G connected call, Tweeted and posted a photo to Twitpic and updated his Facebook status via new 3G masts.

“I’ve climbed Everest before [actually eight times before], but have never been able to share the exhilaration and excitement I experience when I reach the top with those back home.

“I unboxed the new Samsung Galaxy S II at base camp and was excited to be able to not only make a 3G connected call home, but also to use all the other great features like updating my Facebook status, tweeting on my journey up and posting a picture to share my moment with friends.”

Kenton Cool’s ninth climb of Everest was sponsored by Samsung.

Simon Stanford, managing director of Samsung Mobile in the UK and Ireland said: “We’re pleased our new Galaxy S II was the phone that the very first 3G connected call and world’s highest tweet was made on.
