Apple has significantly improved upon last year's original iPhone while extending many of the benefits of its newest model to existing users in the form of the iPhone 2.0 software update. AppleInsider's week-long "Inside iPhone 2.0" series will present a detailed analysis and review of the iPhone 3G, the 2.0 software, the App Store, and push messaging. This first segment looks at the iPhone 3G hardware itself, what's new and different, what's bad, and what's missing. A followup segment on hardware will look how the new iPhone 3G compares to other smartphones, and whether it's worth the upgrade for existing iPhone users.
