Qualcomm and Gameloft have signed an agreement that’ll see the two companies working together to bring high-quality games to mobile phones.

The companies, which have already have a working relationship, will start their new partnership by optimising Gameloft’s 'SpiderMan Total Mayhem HD','Real Football 2011 HD', 'GT Racing: Motor Academy HD' and 'Modern Combat 2: Black Pegasus' for Android-based devices.

America's second National Day of Unplugging, which takes place on 4th-5th March 2011, has a mobile phone application to encourage non-use of mobile phones.

The event is being coordinated by Reboot, a group that's trying to reinvent Jewish culture and traditions for the 21st Century. Reboot suggests that everyone - regardless of background or religion - can benefit from taking a day off to relax and 'unplug' from their working week.

New figures from PopCap Games have shown large increases in the usage and frequency of mobile game playing among US and UK adults.

33.6% of all adults in the USA and the United Kingdom say they've played a game on their mobile phone handset in the past month, with almost a quarter (24.6%) having played in the past week. The figure was much higher for smartphone users; 83% of them had played in the past week.
