For people who are fond of using and sending quotes to their friends, here is a specific reference point you can use compatible with the iPhone. Quote Book from TOMSOFT allows generations of wisdom to be carried in your pocket in the form of a database of 3,000-or-so quotations.

From the uncomfortable to the hilarious, there are numerous categories to choose your quote from, handy for finding something smart to say in a variety of situations. Everything from art, politics, love, marriage, sports, technology, and other subjects are represented. You can also look at your favorites, recent quotes you have viewed, or a random quote.

Once you find a quote you like, you can add it to your favorites, give it a rating, or find out more about the author by viewing their Wikipedia entry from right within the app. You may also e-mail your pearl to a quote-less friend, and share the wisdom.

Quote Book also offers a search feature, but not on the main page; you may only search within the category you are currently browsing. The app normally sells for US$2, but as this review was posted, Quote Book was on sale for just $1.

Quote Book is compatible with any iPhone or iPod touch running the iPhone 2.x software update.
