Worried about calls or text messages coming in to your mobile and feel like having a care taker to keep a watch over these then try TextGuard. The application is compatible with BlackBerry and Windows Mobile phones with the same coming to your iPhone and Android soon. The app works by simply downloading it to your device and then create an account at the site and then keep track of as many numbers as you have to. Sounds like violating my privacy but is definitely useful for concerned parents who want to keep an eye on the young ones. The service is free to try and other wise charges $29.95 a month for 5 devices with 25 Mb of storage space.
