Searching for specific Maps iPhone App!

Hi There...

I'm looking for an iPhone Map app that does the following:

I want to be able to create my own categories (restaurants, etc.) and then enter in my own locations. So when I'm in a particular area, I can click on "restaurants" and it will show me the entries that I have entered.

That's it! No stupid Facebook connections, or what restaurants they think I'd like...

Just the information I enter. Is that so hard? Help!

And Maps doesn't do this sufficient enough for you ?? Granted that there are no "specific" categories section but i have no trouble finding restaurants in any map i goto and i come from lonely Australia. I find if I'm in a region and zoom in as far as i can go there information is quite good.
Cant help you with a specific App though sorry.
