This is the first Samsung phone to use Symbian OS 9 and the first phone outside of Nokia to use S60 3rd Edition (in any flavour). Samsung has previously produced three publicly available S60 phones, but the i520 looks set to be among the most advanced S60 phones available. Outside of the Japanese market it is the second Symbian phone to be announced with 3.5G (HSDPA) connectivity.
We will bring you more information and live pictures and video from the Symbian Smartphone Show tomorrow.
