The newly launched Asus P552w PDA phone features Glide – an innovative touch-responsive user interface that makes navigating and performing tasks on a mobile phone more intuitive and interactive than ever before.

Equipped with a 624MHz processor and a host of market-leading features such as 3.5G HSDPA connectivity, GPS and seamless Google integration, the Asus P552w PDA phone is a perfect fit for the rising tide of young, tech-savvy professionals who appreciate a good-looking mobile companion that packs a wealth of fun features and yet is no slouch when it comes to work.

The Asus P552w also houses applications that enable easy access to web content like RSS newsfeeds, YouTube movies and photos on Flickr, ensuring that users have a full complement of entertainment options to choose from while out of the house or office.

Unlike the original iPhone, which features a metal back, the back of the new 3G iPhone is either ceramic or plastic. (Apple has not disclosed what it is made of; many people have speculated that it is plastic, while others believe it’s a stronger type of ceramic material.) Whatever the case is made of, it’s apparently prone to damage. Some iPhone 3G owners are noticing cracks appearing in the cases of their phones–which are less than a month old.

The iPhone 3G is available in white and black; most of the reports of cracking are from owners of white phones. Some users have noted cracks in black phones, though, leading some to speculate that the cracks are simply harder to see in the black plastic. The cracks range from very small, hairline fractures on the sides and tops of the phones to more noticeable splits along the back.

Posters on Apple’s support forums have indicated that the company is replacing damaged phones. Check your phone carefully–and handle it the same way.
