BlackBerry Tour runs on the carrier’s respective EV-DO Rev. A 3G networks domestically and offers 3G UMTS/HSPA (2100Mhz) and quad-band (GSM 850/900/1800/1900; GPRS/EDGE) support, so you can get voice and data coverage while traveling outside of North America. The smartphone also offers Bluetooth 2.0 (including stereo Bluetooth and tethering) as well as assisted and autonomous GPS, but unfortunately, there is no Wi-Fi. As far as design, the BlackBerry Tour is a blend of the RIM BlackBerry Curve 8900 and the RIM BlackBerry Bold. The device measures 4.4 inches tall by 2.4 inches wide by 0.5 inch thick and weighs 4.5 ounces. There’s a 35-key QWERTY keyboard for easy typing and a 2.44-inch, 480×360-pixel resolution display. That’s good, because much of the Tour’s strength lies in its messaging abilities. RIM is known for its email client, and that’s no different here: as well as Microsoft Exchange support there’s POP and IMAP account functionality, together with instant messaging for the popular formats.
