The i400 runs the Symbian operating system with Nokia's familiar S60 user interface sitting on top of it. It's the second S60 phone Samsung has brought to market - the first was last year's i520 smart phone. By contrast, Samsung sees the i400 as a more mainstream product.

The 92g, 10 x 5 x 1.6cm i400 goes on sale in Russia in July, but will appear on store shelves in other European countries soon after, Samsung said.
