After convergence, toughness seems to be the new mantra of cell phone manufacturers. Casio unleashed the new E03CA cell phone, boasting high levels of waterproof efficiency as well as embodying a shock-resistant body.

Casio entered the cell phone business in 2000, and made a mark for itself with the G'zOne Type R phone. The E03CA includes Bluetooth support and a camera, with a largish 2.4" QVGA screen (main display). The phone is compatible with CDMA 1X EV-DO standard, so watch out for high-speed data access on this baby.

Battery life is claimed at 380 hours on standby and 300 minutes of talk-time. The Casio E03CA weighs in at 166 grams - a bit on the heavier side for those used to the RAZR and its clones. It supports MicroSD memory cards for expanding on the available memory.

The Casio E03CA cell phone is now available to KDDI customers in Japan.
