GSM in 1992?
Ow. I know tech takes some time to get here, but 1992? That's like 10+ years of lagging behind!
TDMA came sometime around 1999, here known as "Digital" because that was the first digital network we got.
GSM must've come some time around 2002, I bought my first GSM phone in 2003, a Nokia 1100.
As for my first phone, well that would be an Ericcson ... hm... can't remember the model, but its the one Arnie uses in "Eraser". Small phone for those days (and maybe these days) standards, but it had a big-ass battery that made the phone fat. Of course, my dad's phone (ca. 1994) was a Toshiba TCP-9300; tall & thin. Both phones were infinitely smaller than the brikphones back then. Oh, and I remember my first phone number: 501-0010!!! (Who wouldn't? Too easy to remember ;)
If someone wants a "phone-only" mobile, look no further than the Motorola F3... that is if you don't mind not having message alerts, reading SMS one *word* at a time or doing well, most of the stuff you're used to. (I think my original Ericcson was much easier to use than the F3, mind you...)
