Dual SIM mobile phone

My work entails frequent travel across the country. I carry two mobiles, one personal and the other, official. Is there any mobile phone that supports two SIM cards, so I can be spared the hassle of carrying two mobile chargers and handling two systems?

Ranjith K Dual SIM mobile phones have now been introduced in India. These support two SIM cards in a single handset, so users can switch between two numbers or networks. Depending on the mobile model, you may use a combination of one CDMA sim card and one GSM sim card, use either both CDMA sim cards or both GSM sim cards.

In India, Spice Mobile launched the first dual-mode mobile phones. It offers two variants, D-88 and D-80. The D-88 Supports both GSM and CDMA, on the other hand the D-80 can support two GSM connections. The D-88 supports 1.3 megapixels camera, with 262K color TFT display, MP3 playback, etc.
