I am getting a few error messages like unknown certificate and untrusted application on my phone. Why is that so?
Since the MTring is a relatively newer application, some of the security licenses, particularly on phones older than one year. Rest assured, this error comes only because they see the MTring as an alien application, and has nothing to do with the security of your phone, as it has been checked throughly to make sure it does not cause any kind of software or hardware damage.
