The best phone doesn't really mean that it has the best features, the way I see it, is that the best phone is the one that totally changed the history of phones, and I think that the 5110 is the one that made people start buying phones (some people bought it just for the games. and even though it didn't have the best features at the time it was a big breakthrough!
The nokia set i have ever used was 3310. Though, it wasn't full of features but i remember that once it fell down from 3rd floor to ground floor and after giving it a hard reset it started working again miraculously.
There are available different types of the mobile available in the market as Nokia. I prefer to use the mobile as Nokia 2730 Classic. The reason is that it provides 3G features in the reasonable price. It helps into video calling and access the Internet as fast.
I have ever used Nokia 6610, Really best mobile and great features at that time. Best polyphonic and monophonic ring tones and FM facilities, Nice compact and slim design, Much comfortable for typing massage. Great mobile phone which one I used long time.
