Blackberry
I can only have 8 choices, so I had to stop somewhere. Obviously the Blackberry was a great device, but there was no room.
@jon There's one option missing: "I don't remember anymore".
It's been decades now. I got my first one in the 90s. One of those bulky ones with a flip thingy and an antenna and stuff. Can't remember the brand for the life of me.
@jon Alcatel One Touch Easy Dual-band
After walking it all over the construction sites the battery cover is hold with a zip tie and the antenna plastic is broken, but the metal is intact: no problem for TX/RX.
I had it with a cloth cover, but the area of the keys that was transparent, well...looked like brown sunglasses.
It still running, also the battery been built to be replaced by normal dry batts in case of needed.
