Firstly, it looks as though Amazon will be announcing an Android-powered tablet tomorrow. Called the Kindle Fire, it probably won’t be a direct replacement for the Kindle e-book reader but an alternative.

Ian Kilpatrick, chairman of IP security specialists Wick Hill Group, writes:

Smartphones are spreading throughout the business world. Their use is growing across organisations and at all levels.

According to Gartner, sales of mobile devices in the second quarter of 2011 grew 16.5% year-on-year. Smartphone sales grew 74% year-on-year and accounted for 25% of overall sales in the second quarter of 2011, up from 17% in the second quarter of 2010.

Samsung Electronics says its Galaxy S II Android-powered smartphone - also known as the GT-I9100 - has achieved 10 million global channel sales, just eight weeks after passing the five million mark.

JK Shin, President and Head of Samsung’s Mobile Communications Business, said "Since its launch in late April 2011, the GALAXY S II has seen continued sales success, demonstrating Samsung’s industry-leading capabilities in - and commitment to - the smartphone market."

Premium rate telephone service regulator PhonepayPlus has started a ten-week public consultation on app-based mobile payments.
