First Mobile Misuse?

Another quote from Constant Touch points toward SMS as being the first major misuse of the mobile phone:

Text messaging was an accident. No one expected it. When the first text message was sent, in 1993 by new Nokia engineering student Riku Pihkonen, the telecommunications companies thought it was not important. SMS – Short Message Service – was not considered a major part of GSM. Like most technologies, the power of text – indeed the power of the phone – was discovered by users. In the case of text messaging, the users were the young are poor in the West and East.
