Well, let's see how we get on. If Nokia refuse to cover the usb connector then we could try:

a) create a temporary website with a petition. Everyone who has had problems could sign it.
b) inform major news sites about the site
c) contact major shareholders of Nokia and direct thier attention to the site too
d) inform your government representitive and maybe put some pressure on Nokia

It is company policy for many corporations to delay fixing stuff like this as long as they can, hoping the consumer gives up.

For the record my usb connector is rock solid. My cat kicked my charging n900 off the table but so far n900 is fine.
