Shop from your iPhone using web apps

The new iPhone 3G has some pretty impressive features, but the most compelling may be the use of web applications. Web apps allow for developers to create their own content. Apple will even help guide you through the Developer Connection with tutorials, videos, sample codes, and reference libraries. You can sign up for a free Apple Developer Connection, which will give you access for submitting your own web app.

The first to take advantage of Apple's web apps for e-tail is AOL Shopping. Their web app has the same functionality as their website - allows the user to search information about the products, read product details, get links to where the items are selling online, and get phone numbers, addresses, and directions to stores - all on your iPhone.

AOL Shopping uses their massive search engine to find the best prices on products offered from multiple retail outlets, such as Amazon, Barnes & Noble, and Target. Enter your zip code to calculate shipping and tax. You can see available stock and purchase with the touch of a button. So imagine this: You go to a store to find that they are sold out of your product. Instead of calling stores and waiting for someone to check stock, you can bust out your handy iPhone and see for yourself. Not to mention, you can compare prices from a slew of retailers. Genius!
