About 1996-7. Had a couple of little Nokia and Ericsson things over about 5 yrs, STILL better than the new crap that has an acre of glass in the front. They fitted in pocket with other stuff, you could read them in the sun (!!), you could do stuff by feel and with one hand, and they'd (mostly) survive being dropped.
Anyway, late 90's my mate got the Nokia thing that was extendable ...... cos he saw it on Swordfish

It was proclaimed at the mini-maxi phone cos it looked like a chick's pad. His coolness rating dropped...
So I got the first thing with voice activated dialling. At a party my mate picked it up and said "d1ckhead" and my other mate's phone rang. lol It picked up on the "i" sound and rang Billy.
Awkward. Until he then said "slut" and it called his girlfriend. Then I was in major trouble
