With iPhone 3G coming out tomorrow amid so much expectations, Apple has launched iPhone App Store today. You can get access to the App Store by doing the following. But, without the Apple 2.0 software you can use these applications. 
- Download iTunes 7.7
- After upgrading iTunes, access the App Store
With over 500 applications available for download at launch, there are more than 135 apps that are free for anyone to download!
TechCrunch has a bunch of screenshots available from the App Store!
