Due to the increasingly fierce market competition, rolling out more new mobile phones of different kinds to deal with different consumer markets has become a consensus among major mobile phone giants. Apart from releasing several mobile phones targeting at fashion and business last month, Samsung recently unveiled two mobile phones with large-capacity memory on the network. One is Samsung SGH-F310 music mobile phone with ultra-large 4GB memory, and the other is Samsung SGH-i450 adopting Symbian system and S60 software platform, with built-in 1GB memory and support for storage card expansion.
