About 1991 - analogue phone the size of a brick - provided by my employer so that they could call me ... if I dared to make a call to anyone except them there was a serious inquest over the monthly bill.
I loved it because it had an FM radio built-in, so I could listen to the footy commentary on a saturday afternoon. Can't remember if I bought it from QVC or somewhere on the high street, but would have been late 90's.
I then had the Nokia 3310, Nokia 8310, Sony Ericsson W810i and the Nokia N8 (My current phone).
I had a brick when we started our own business, as there was only the two of us. When I used to pick my then, 7 year old up from school, I would pray nobody would ring me. I would have died of embarrasment.
The prototype handheld phone used by Dr. Cooper weighed 1.1 kg and measured 22.86 cm long, 12.7 cm deep and 4.44 cm wide.. The prototype offered a talk time of just 30 minutes and took 10 hours to re-charge.
Click on the pic you want, tiggs, and it should alter the page to say "View original image." If you do that and then the right-clicky bit, that should help.
