After playing wiht my new Nokia phone for a while and thinking about what I'm still missing, I thought of this:
Contacts have a field for birthdates. What do you do on someones birthday? You call them of course. Unless like me you forget.
Given the potential additional revenue this feature would generate for network operators, I am completely baffled by the fact that no product manager discovered a feature that automatically reminds me of birthdays as soon as it discovers any in my contacts.
Pre-install it on the phone and have it enabled by default - seems so plain obvious.
Any other features you would like to see? (maybe a Nokia product manager reads this)
