I love my nextel i90c phone. I have had cellular service with Cingular and Centennial. I currently have the nationwide unlimited plan and I use approximately 3200 minutes a month. No other cellular service provider has such a plan that can cover an unlimited amount minutes a month for such a low price. I am extremely happy with nextel and have recommended the same to friends and relatives. One of my closest friends sells Verizon and although Verizon has more towers the two way capability of Verizon is there but the delay in two way talk is very aggrivating and to locate the next user usually takes about 20 seconds. Also I have not had any problems with battery life on my phone. It is recommended that you turn off your phone when you charge it so that it charges fully and I charge my phone at night when i go to sleep.
