The BlackBerry Storm is a touchscreen smartphone developed by Research In Motion (RIM). A part of the BlackBerry 9500 series of phones, it is RIM's first touchscreen device, and its first without a physical keyboard. It features a touchscreen which reacts physically like a button via SurePress, a Research In Motion patented technology of providing haptic feedback. It is intended to be a direct competitor to Apple iPhone 3G, the Palm Pre, the T-Mobile G1 by HTC and the HTC Touch family.
The Storm has received mixed reviews from critics, with some finding the Storm's touchscreen difficult to use or discovering bugs and glitches with the phone's software, but some have praised the Storm for its call quality and its business-oriented features.

The BlackBerry Storm2 is RIM's second full-touchscreen smartphone. Unlike the original Storm, the Storm2 features Wi-Fi as well as a redesigned outer shell.
The phone's codename throughout development was "Odin." The model number is 9520 for the GSM/UMTS/HSPA model offered by Vodafone and 9550 for the CDMA/EV-DO and UMTS/HSPA model offered by Verizon. The Storm2 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 phone has been a reasonable commercial success.
When comparing the Storm2 with the original Storm, users find the Storm2 more user friendly. The new multi-touch screen allows users to type at a much faster pace- it has two finger recognition.
Research in Motion recently released specifications on the phone, reporting that 256 MB of RAM will be available for applications, doubling that of the original Storm. One major change is that the method of input, SurePress, has been redesigned. Instead of one physical button that lies in the direct center of the screen, the Storm2 has four piezoelectric sensors located on the four outer corners of the screen that allow for confirmation of input. The screen does not depress when the device is locked or off. It ships with the new BlackBerry 5.0 OS. The phone's SureType screen, which was heavily criticized on the original Storm, has been revamped and improved. The Storm2 also supports OpenGL ES
