If Blackberry or the company who now supplies the phones wakes up and realizes they current I-Phones and Android phones are not in any way secure for user information they can make a big comeback with the security they do offer. I read the Android phones are being monitored by Google for location tracking and sell the info to marketing companies for adds on user devices. I looked at the Google site and found this on how to do it.
