Wireless carrier AT&T and mobile phone maker Sony Ericsson announced today the launch of two new mobile phones in the United States, namely the Sony Ericsson C905a Cyber-shot and the W518a Walkman devices. According to the companies, the two handsets are capable of providing a leveraged social networking experience to mobile phone users in the country, while also being designed to encourage self-expression and to deliver enhanced photography capabilities.

The new Sony Ericsson C905a Cyber-shot comes to the carrier's airwaves with an 8.1-megapixel photo snapper, becoming this way the highest resolution cameraphone available with AT&T. Moreover, the phone's camera also comes with attractive features, including face detection, auto focus, xenon flash and geo-tagging.

The second new mobile phone, the W518a Walkman, includes a variety of entertainment features, such as conversational messaging, leveraged Facebook connectivity, attractive music capabilities, as well as a 3.2-megapixel photo snapper. The two companies also announced that those interested on learning more about the W518a should follow the W518a Facebook page here.

“Sony Ericsson has created two signature phones that enhance the quality of photography and social networking on a phone and take advantage of exciting AT&T services like AT&T Navigator and Video Share,” Michael Woodward, vice president, Mobile Phone Portfolio, AT&T Mobility and Consumer Markets, says. “The C905a is the best camera available in a mobile phone today and the W518a’s unique Facebook user interface and Walkman music features will elevate how our customers express themselves.”

According to the wireless carrier, both the new Sony Ericsson C905a Cyber-shot and the W518a Walkman are expected to become available for purchase on the company's site and at AT&T stores starting July 19. The C905a Cyber-shot device, the carrier adds, comes with a price tag of $179.99 with a two-year contract and after a $50 mail-in rebate. The W518a Walkman comes with a price tag of $49.99 under the same conditions. The mail-in rebate will turn into a $50 AT&T Promotion Card, the carrier explains.
