I just got a Nokia C2-02 for Xmas....did you find out the answers to your question? I have always had nokia's before and liked them but never one that could connect to the internet etc etc. One of the main things, I was wondering if you found out was - can you increase the length of time the backlight for want of a word stays on. I am finding that even sending a text ( I am slow at texting), the screen blacks out in the middle and I have to unlock the phone, to continue.
I do know you got yours in 2011, but we in New Zealand are a bit behind the times...:)

Thanks Gail
