Last week, French iOS security researcher pod2g revealed a potential security risk with the Apple iPhone’s handling of SMS text messages.

All text messages can be sent with an optional ‘reply to’ telephone number that’s different from the sender’s number. The majority of text messages don’t use this feature - and many phones either ignore the extra data or display both numbers - but Apple’s iOS seems to handle it in a potentially risky way.

However, all's not well in the world of mobile retail - as mystery shopping by a consumer organisation reports widespread misinformation from sales staff.

New figures from digital security company Kaspersky Lab show that the number of new malicious programs targeting the Android platform has almost trebled in the past three months.

The second quarter of 2012 has seen over 14,900 new malicious programs targeting the Android OS. In Q1 2012 there were just under 5,450.

Juniper Research is forecasting that the ‘bring your own device’ trend will see the number of employee-owned smartphones and tablets used at work more than doubling in the next two years. By 2014 there’ll be 350 million personal mobile devices being used at work, compared to less than 150 million this year.

It means almost 23% of all consumer-owned tablets and smartphones will have a business function as well.
