NAreaCodes 0.4 - This app is a Formula template. That is, it installs itself in the Newton's Forumulas app list. This is where you'll normally find the metric and currency converters and the loan calculators. Now, you'll have an area code lookup database in there as well. There is one field for you to enter an area code. Enter one and tap the Find button to the right of the entry field. nAreaCodes will lookup that area code and display what area is covered by that code. If you enter an invalid or unknown area code, it will display "Not found".  This app will expire 30 days after you install it.
