maybe because Nokia is a phone manufacturer...?

I agree, it should be 789 on the top.

Also, I have another gripe about the small onscreen keyboard: Why is the "+" key next to the "0"? I would much rather have the "-" key there. In 8 months of using this keypad for entering URLs, I have never used the "+" key but I have used the "-" key many times. I think the up arrow on the shift key is becoming worn off!
