Sir, I don't remember having seen the domain bt.cc before, but you appear to have my cell phone number where you sent the above message. Could you explain where you got my number?
If that's the case, I would like to see the answer posted by the OP.
Cannot believe there is still 1 app in existance that doesn't try to copy one's phone book. Cellphones have been made for stealing data. Naturaly those end up on sale somewhere.
How is the App supposed to keep ballances safe? I assume there should be as least trust onto the hardware platform as possible. Maybe a second factor auth using one time passwords distributed on paper.
