Interesting idea
So here goes...
I stumbled across this site while working on Nokia's N70 in 2005 and stuck around because it promotes discussion without the flaming that so often occurs on forums (even the moderated ones).
Although I no longer work for Nokia, or indeed on mobile phones at all, I still know people who can help, and pass on any problems you guys are having. I have my finger in several (own business) pies at the moment while holding down a full time role as an IT systems architect... so if any of you admit to any useful skills I may have to pick your brains
The N70 I got given during development was my first 3G experience (previously only ever using a mobile for SMS and (incoming) calls), and it was great to try it all out without having to pay for it

I switched to Vodafone after years on O2 mainly due to the customer service in the shop when I went in to buy a SIM (as I'd already got my own SIM free phone from Nokia). I know I'm not using all the funky 3g features as yet, but I think that's mainly me trying to keep my phone bill down

- couldn't do without the streaming tv though - great for "at desk" entertainment
Look forward to reading about the rest of you ...
