Well I returned my second captivate yesterday for good. In all I had them both for 5 days each. This one I had loaded not a single app nothing the only thing running was email ( and not allowing auto get) texting and a few phone calls. I never used the browser nothing else. When this one started shutting down ( power mode off) I called Samsung, and they not only denied any issues, refused to send me a battery and said well send phone in for evaluation. I laughed at them. I finally decided that no phone was worth the time effort and aggravation this one was causing. Interestingly when I called ATT to reactivate my old apple G for time being they said oh yes we have many issues with the captivate. You should return it. When I returned the phone to best buy they denied any issues and were selling one right then and there, I told the guy you probably will be fine I am jinxed ... Any how Samsung has a real problem and when another manufacturer makes a  decent android phone for ATT I will try again. ( as I have two accounts and my apple 4g is on my other line,) as much as I love the I phone having two I phones create issues with ring tones, and phone books I had to merge them for now. I also must say the battery life on the Samsung was very poor. Good luck to everyone else trying this phone out.
