And another follow up on the history trail of the first GSM call in a commercial network 20 years ago to the post about the state of GSM back in 1991 to one of the first GSM phones, the Siemens P1. Obviously, the Siemens P1 big and heavy but even then it was clear that the next step in miniaturization were real "handheld" devices as shown in this video clip from the 1991 international radio exhibition (IFA) in Germany. One one of the first truly mobile phones was the Nokia 1011, announced at the end of 1992. And here's the TV commercial from back then. Enjoy!
