Cell Plus

Many phones are offered by only one carrier. However, the Blackberry Curve offers at least five models from four carriers: Sprint, Verizon, T-Mobile and AT&T. The 8520 and the 8900 are offered by AT&T and T-Mobile. The 8530 is the Verizon or Sprint offering. Curve 3G models are offered by all four carriers as well. The designs are virtually the same with the traditional Blackberry block design, the Qwerty keypad and trackpad and the PDA capabilities. These smartphones are business workshorses. Their keyboards make messaging quite easy. They are not quite as big as some Blackberrys, past and present.
