July 11th marks the entry of the newest iPhone baby into the world, the iPhone 3G.

Apple has given us a video guide and a FAQ for all the details. One of the coolest things revealed today was the UI and the download process for the upcoming App Store, which will be released with the iPhone 2.0 firmware.

The new Apple guide video shows us that users will download apps the same way they download media through the iTunes wifi store. All you’ll have to do is press a “Buy Now” button, at which sends the users back to the home screen. An app icon will then show the progress of your download at it zooms directly from the cloud to your phone.

The new AT&T FAQ page also outlines the price plans for the new iPhone 3G. Unlimited data and talk time will go for $129.99 per month, with unlimited texts costing an additional $20.
