Ten Free Killer iPhone Apps
WhitePages Mobile app
Plenty of phone directories are on the Internet. But WhitePages Mobile is an incredibly handy resource for finding home and business numbers on the fly or doing a reverse phone lookup (you have the number but have no clue whose number it is).
When new listings pop up, you can add them to your contacts or update existing contacts. You can also get maps and directions to where folks live or work. In some cases, WhitePages Mobile provides other information, including the age range of the person and some of the other people living in the person’s household. And WhitePages Mobile uses GPS to detect your current whereabouts.
