What makes a good iPhone killer? Is it a big touch screen, a built-in camera with a huge megapixel count. Is it connectivity options like 3G and HSDPA? Is it the added GPS capability?

The Samsung Instinct, whch is exclusive to Sprint, the U.S.’s fourth largest mobile carrier, boasts a feature set that includes built-in GPS, Sprint TV and Microsoft Live Search navigated by a fascinatingly user-friendly UI. This UI resembles the iPhone’s UI closer than all other iPhone competitors. On top of that is a Haptic technology that gives tactile feedback to the virtual buttons.
