best business search app?

[heyp]

currently i'm using YP mobile but i've found it doesn't always deliver what i'm searching for and it's kind of slow, but i really like it's integration with the maps app on the iphone... i used to use yelp but their maps really sucked (not sure why they didnt integrate with the maps app)

so what's the best business search app for the iphone?

Yellow Book has a web app that is MUCH better than Yellow Pages.
