25 apps that are going Apple (RED) for the holidays

About six months ago, Apple approached the designers of some of its most popular app-store products and asked them if they would modify them to help promote the company's two-week fundraising campaign (from Monday through Dec. 7) for (RED), which fights the spread of HIV/AIDS particularly in developing nations.
