Please no privacy complaints... My 13 year old daughter now has a captivate to match my own. I am new at this and frankly, got these 2 phones so I can keep track of her whereabouts. She is at a critical age and unfortunately has been making some bad choices as of late. it is just the two of us and this may help me avoid a potential disaster. Are there recommended apps that will work on the captivate to provide me with simple real time tracking of her (phone) and do so quietly in the background? I know she wont go anywhere without it...
