I had Nokia 3310, 3510i… and then I switched my phones like every year because I even worked in the space.
Mostly I just got a good deal on some refurbished used ones.
Most entertaining was Nokia N-Gage QD which was far ahead of it’s time…

This bad boy?
No, this one. It was able to run ~ PS 1 games, but cartridge with the game was basically a normal SD card, and it wasn’t hard to crack the games for free. So basically only few of the games ended up in profit, which means no publisher wasn’t willing to take the risk… and N-Gage quickly became history.
Now, with internet the mobile gaming is THE THING worth of billions of dollars, but back in the day, it was a risky endeavor. 
Yeah, I remember that one. Such a crazy phone.
