Yes the new iPhone 3G S is fast, the camera is improved and the voice control is a welcomed addition. Two days in as a new user of the iPhone 3G S, I must say the enhancement I first noticed is the oleophobic screen. The oleophobic screen is said to be finger print resistant, and it is, it is a definite improvement over the screens from the original iPhone and iPhone 3G.
The feel of the new screen is different from the previous screens, not bad, just different. Bottomline, the new screen is a step forward, showing fewer greasy fingerprints and providing a surface that wipes clean easier than the previous screens.
