아이폰 3G VS 아이폰 3GS

What's the point in buying a new iPhone if it looks exactly like the old one? Because once you start using it, the speed of the iPhone 3GS will amaze you.

Like we said, from the outside the 3GS is exactly the same as the 3G. It's slightly heavier and has glossy text on the back, but if Steve Jobs whipped one out in public before it was announced, you wouldn't have been able to tell the difference.

By holding the 3GS next to the 3G, you'll notice that the screen is slightly more reflective because of the new fingerprint resistant oleophobic coating. It even has a little bit of a rainbow effect if you reflect a monitor with it. Surprisingly, the coating actually works in preventing a good deal of fingerprints and face grease, and it allows the phone to still be smooth and usable even if there are fingerprints on the surface.

 

The 3GS display is ever-so-slightly warmer than the 3G's, having a yellow/orangish tint when viewed side by side. If you remember, the 3G's screen was also warmer than the 2G's. It's not distracting in any way, and the warm screen is slightly easier on your eyes even if the brightness is bumped up high.
