Siemens SX1

The Siemens SX1, codenamed K1, is a stylish Symbian smartphone announced in February 2003 and released in December of the same year. It was the first Symbian device that was not manufactured by Nokia, and was the only one ever manufactured by Siemens. Other models in the Siemens SX family were Pocket PCs.

The SX1 was one of the most powerful phones at the time of its announcement, but its release came almost a year later.

It is known for its unusual keypad layout, with two columns of six keys on the left and right sides. The pre-loaded game Typegun was intended to help familiarize users with the layout.

Prototypes of the SX1 had only the digits printed on the keys, with the corresponding letters written on the display bezel, while retail versions have both digits and letters printed on the keys themselves.

Thanks to its OMAP chipset, the SX1 saw a port of Linux using the Das U-Boot bootloader. This is not yet possible on Nokia's OMAP based smartphones.
