What is the highest MP camera phone available?

I assume that the MP rating on a camera is what determines the resolution and thus the extent of zoom and enlargement of the photos.

My question is . . . what is the highest MP camera phone available for use in the U.S., specifically for use in southern california?

I was thinking about the Nokia N95 with 5MP, but wanted to know if anybody knows of another phone that has a higher resolution camera on the phone?

Please let me know.

Am I the only person who really likes to have a great camera on a phone? or has this question already been answered some where else?

Again, I assume that MP's is what determines the "High Def" resolution of a camera and the pictures it takes, and thus why I asked the question. If anybody knows otherwise, please let me know.

Is the Nokia N95 5 MP resolution camera phone the best camera phone that we can get and also have activated and use for mobile phone service in the U.S. or rather more specifically in Southern California?

Thanks for any and all input.
