I want to buy Samsung Finesse mobile phone but I have some confusion so I need your advice guys. Yesterday one of my friends bought the same phone and I found it completely awesome. It has a fine touch screen and an easy-to-use TouchWiz interface. I want to know more about its features; like I have heard that it is also having 3G EV-DO and GPS like features too. Tell me something more about this phone and also explain that can I use different apps in it?
