Apple's own Apple Store app for the iPhone received a small update this week that improves search features. The app lets users shop for Apple products and accessories, set up Genius Bar appointments, and complete in-store purchases.

According to Apple's release notes, the update also includes "various performance enhancements." What isn't mentioned, however, is word of rumored free giveaway incentives for making purchases through the app. Assuming that feature is coming, we'll just have to keep waiting.
The Apple Store app is available as a free download at Apple's iTunes-based App Store.
