The early N95's had thier problems, I had mine the day it came out (original silver) , and to this day I have never had any issues with it. A lot of problems were to do with 3rd party software as far as I can remember, with Orange being a particular problem??
Mine has always been on 02, and been fantastic, and I will be keeping it as a second phone (for work as I work in a dirty/physical job so phones tend to get ruined quickly!) alongside the i-phone.
Each brand has it's merrits and flaws, it is a bit like comparing a Ferrari to a Lambo, each is fantastic for different reasons IMHO
