I've had my a900 a week after it was released, and since then I've had some issues with it. For one when I receive text messages, it doesn’t show the persons name if I have it stored in my phonebook, but sometimes it does.

The problem you are having with only the number showing up and not the name when you get text messages was a problem that I had initially.
