To slim the 7100t down to 4.7 x 2.3 x 0.8 inches and 4.2 ounces, RIM replaced the BlackBerry thumb-keyboard with one that uniquely merges a keypad and a keyboard. For text entry, each key supports two letters, while predictive text software called SureType helps you accuartely input text—so when you press a key the 7100t knows which of the two supported letters you mean to use.

Since the 7100t is a quad-band (850/900/1800/1900 MHz) GSM/GPRS mobile handset, you can use the smartphone when traveling anywhere in the United States, Europe and Asia, as well as many other parts of the world.

Other features include Bluetooth for use with wireless headsets and other peripherals, a bright color screen, and 32MB of RAM with no way to add more memory because the 7100t does not integrate a memory card slot like most other smartphones. Of course, the 7100t can connect to RIM's renowned enterprise software, BlackBerry Enterprise Server, for access to corporate e-mail and data.
