Since its debut a few years ago, the Apple iPhone has raced its way to the top of the global smart-phone market. Today the iPhone commands a large chunk of all smart-phone sales, largely due to its ease of use and highly customizable options, such as the Apple App-Store. A mindboggling array of useful iPhone utilities can be found in the Apple iPhone App-Store enabling infinite customization opportunities for your phone - everything from the latest 3D games to time-saving productivity software are a few taps away for any iPhone user anywhere in the world.

Here are two apps that every iPhone user must try:

The first, Marq, is one of those quirky little apps some iPhone users simply love and others love to hate. Marq is a simple program that essentially turns your iPhone into a scrolling marquee - perfect for those who want to get their message across in a playful yet effective manner. Viewable from as far as ten to twenty-five feet away, Marq makes sure you get your point across. Building an eye catching scrolling marquee is as easy is typing in some text, setting the color and scroll-speed. The Marq iPhone utility makes it easy to communicate with someone from across the room during a business meeting, can be used as a playful way to flirt with a member of the opposite sex, or can even double as an impromptu show of support for your favorite sports team during a live game. You're sure to come up with your own unique and fun use of the Marq app for your iPhone.

Our second app, iRibbit, is one no eBay user can afford to be without. iRibbit gives you complete control over eBay auctions in a portable and easy-to-use package. This powerful little utility ensures that you never miss out on that great eBay deal when you're away from your computer. eBayers concerned about the security and stability of such apps will be pleased to know that iRibbit has built a strong reputation over the years as a robust, secure and simple bidding utility for your iPhone - it even won first place in eBay's International Widget Contest. iRibbit lets you bid with confidence on the go - it is one of the few auction utilities that has passed eBay's stringent quality assurance requirements and proudly bears an eBay Compatible Application logo.

Hardcore eBay users will want to take advantage of iRibbit's many unique features that make the entire bidding process easier and give them the competitive edge in winning auctions. The countdown timer, for example, notifies you to the last second the time left on an auction. You can even add items to your watch-list, search through eBay's massive database of auctions, and much more.

iPhone apps are the perfect addition to your smart-phone experience. The app-store provides endless customization options as well as turns your phone into a powerful media player and communications device. New and innovative iPhone utilities are released every day that give you the chance to interact with the world around you in a whole new way. Whether you're looking to have a bit of fun on the go, or run your eBay business from your pocket, there is an iPhone app to match your needs.
