This is an all-time classic. No description needed.
Nokia 3330The same as above, but with one extra game and now unused WAP connection. Trying to get it up and working, though.
Nokia 8110
The Matrix Banana. Simplistic OS, but the slider and the banana-ish shape makes it really cool.
Nokia 2760
Cheap flip phones final boss. Can't say it's reliable, but i still like it's compact, plasticky shape.
Nokia C5
It's the most reliable phone with good Internet connection speed and fast OS (even though s60v5 is mostly frowned upon by the society).
