Mobiles linked to disturbed sleep

Using a mobile phone before going to bed could stop you getting a decent night's sleep, research suggests, reports BBC News. The study, funded by mobile phone companies, suggests radiation from the handset can cause insomnia, headaches and confusion.

It may also cut our amount of deep sleep - interfering with the body's ability to refresh itself.

The study was carried out by Sweden's Karolinska Institute and Wayne State University, in the US. Funded by the Mobile Manufacturers Forum, the scientists studied 35 men and 36 women aged between 18 and 45.

Electronic Arts, the computer game publisher, has signalled its intent to embrace new, Internet-based business models, announcing a version of its popular Battlefield title that will be distributed free online, says Times Online.

Battlefield Heroes - a slimmed down, cartoonish version of its popular combat game - will be released for PC this summer. Instead of being sold for around $20, it will be available as a download for no charge.

The makers aim to generate revenue through advertising and sales of weapons, outfits and other "virtual items" that can be used in the game.

Dell will add a new series of blade products to its PowerEdge server line, expanding its presence in a market dominated by rivals IBM and Hewlett-Packard, reports PC World.

The PowerEdge M-Series of blades includes the fastest-performing and most power-efficient blade servers the company has, said Mike Roberts, senior product planning manager for Dell.

The PowerEdge M1000E, a 10U enclosure, will support the new Intel-based PowerEdge M600 and Advanced Micro Devices-based PowerEdge M605 blade servers, also announced yesterday.

AT&T has unveiled business plans for Apple's iPhone, marking the first time the mobile carrier has courted corporate customers of the smartphone. But the lowest-cost data plan is still two-and-a-half times higher than a comparable consumer plan, states PC World.

The news comes on the heels of reports - still unconfirmed - that IBM will soon add support for the iPhone to its Lotus Notes enterprise messaging system.

AT&T's new iPhone plans for businesses, which it spelled out on its Web site, come with a minimum two-year service agreement. Unlike its consumer iPhone plans, however, which combine voice and data into one fee, AT&T's business billing splits the two.
