Today Samsung Electronics launched its new SGH-D780, a dual-SIM handset. But beyond supporting two SIM cards at one time, the D780 can actually receive calls on both SIMs simultaneously - just as if the user had two phones. The D780 user can switch back and forth between active calls with a simple press of a button.

Such a device is perfect for business users that don't want to carry a separate phone for their personal calls. The D780 is similar in capability to Samsung's first dual-standby device, the D880, but instead makes use of a simple bar form factor instead of the D880's slider design.

The Samsung D780 sports a 2.1" QVGA resolution display and a 2 megapixel camera. A built-in FM radio and MP3 music player are also available for passing the time between calls. The D780 can be connected to a PC via USB 2.0 or Bluetooth, and the Bluetooth system even supports the A2DP stereo profile for use with wireless stereo headphones.

The tri-band GSM (900/1800/1900MHz) SGH-D780 comes equipped with a large 1200mAh battery, and measures 15.7mm (.6") thick. This cell phone should go on sale in Russia next month, with Europe, Southeast Asia, and the Middle East seeing the D780 shortly thereafter.

Hi! Samsung SGH D780 is just wonderful. Two phones in one. My only problem is how to check the contents of the memory card such as downloaded files. How do i go about it without connecting to the PC? JO
