I purchased this phone in June. About a month after using it it started acting "funny". It kept ramdomly shutting off and the battery would not stay charged for more than 2 hours. I returned the phone to Cingular and they game me a new one. The "new" phone stays charged longer and doesn't shut off randomly BUT it will say that is has full signal, then you go to make a call and as soon as it connects the signal drops to nothing. It will say you have full signal while you are talking on it but the person on the other end can't hear you speak. Also, it will have signal in places that no cell phone would and have no signal in places that every cell phone would.
