Reviving the flip phone format, Philips has come up with a cool looking phone that promises non-stop chat for about eight hours (or up to 850 hours of stand-by time) before juicing it up again. Dubbed the “Xenium X530,” the clamshell phone concept is conceptualized by a Chinese company and boasts Tri-band GSM/EDGE connectivity (900/1800/1900 MHz), 2.2″ wide display screen with 240×320 pixels and 262K colors. The Xenium X530, complementing its elegant flip cover, also includes 1″ OLED external display, Bluetooth 2.0 with A2DP connectivity, music player support, an integrated FM radio with RDS and 2-megapixel camera. Though there is no word on pricing and availability at the moment, the Xenium X530 will be available in Asia and Europe soon.
