So here is the new Sony Ericsson T715 HSPA Slider Phone , it looks great and it’s slide feature is what make it just like Nokia 
. Anyway I believe that this phone s an innovation of their previous model. You can check the specification in the links provided above.
Sony is now having it’s move to compete with the iphone, I am referring to Sony Game gear hybrid Nikkei.
Sony Corp is considering developing a cellphone-game gear hybrid in a bid to better compete with Apple Inc’s highly popular iPod and iPhone, the Nikkei business daily said on Saturday.: Source : Reuters
So will this future innovation of Sony will be a greatest threat to iPhone ? Many have tried but until now iPhone have the market. So let us just wait until the Sony PSP phone will be launch.
