The BlackBerry Storm 2 is the first and only smartphone in the world to have a full clickable touchscreen powered by its piezoelectric sensors underneath the screen.
The Storm 2 comes with 2GB of on-board flash memory — 1GB more than the original — and is bundled with a 16GB microSD card (though not by Vodafone).
The new screen allows users to type at a faster pace—it supports multi-touch as introduced on the iPhone and available on Android-based devices.
RIM released specifications on the phone, reporting that 256 MB of RAM is available for applications, doubling that of the original Storm.
