Now, that we've had a little time to play with it we can confidently say that the new iPhone is a nice upgrade but ultimately not an essential one for most. For users that have been using the iPhone as a gaming platform mainly or coveting the ability to take video with their cell phone, the iPhone 3GS may be worth the upgrade price. Bumps in both processor and RAM allow the 3GS to load comparatively faster and display better frame rates than its predecessors. It is most noticeable while playing games with more graphical output.
