Iphone 4s (bought it in 2011 and Still using it, serves me well dont see a reason to upgrade it yet, apple support for their phones are unmatched)
Samsung Galaxy S4 (bought it from Ducknuckle for my GF, she said it was too big for her, now im using it as my business phone)
few I remember
Nokia, 1610, 5110, 6110, 3210 and various others before I got a Samsung D910, SE K810i, went back to Nokia with a Talk Radio (at the time a game gift voucher was more enticing), Nokia 1202, Samsung D910, Iphone 4, Sony Xperia (first Sony without the E) Samsung S4, S5, back to a Nokia 1202 for a while, Vodacom Smart Steppa, back to S4 and now have an S7.
The phones that stood out for me from the lot:
Nokia 1610, 5110, 3210 and 1202. Purely due to durability, also my 5110 was rebuilt from spare parts so many times it was hardly the same phone in the end.
SE K810i Still think it was an awesome phone, beautiful to look at, lovely to hold and the buttons were pure sexy.
Sony Xperia, First Android. Also, had hdmi and that expanded it's uses many years after it was retired (including amongst others using it as a plex player/media player).
S5, sexy and ADH.
