When the iPhone 3G goes on sale tomorrow, more than 500 native applications will be available on the revolutionary new App Store — including more than 125 free applications. And when they find applications they want, customers can wirelessly download them directly to iPhone and begin using them immediately.

In his review of iPhone 3G, Walt Mossberg (allthingsd.com) considers it “much, much faster” than the original iPhone. In fact, he found that “ doing email and surfing the Internet typically was between three and five times as fast.” iPhone 3G was just as fast handling Mossberg’s corporate email, which, he says, “was pushed to the phone as soon as it was received on the company’s servers.”

Having tested the new iPhone 3G for more than three weeks, Ed Baig (usatoday.com) states that “with GPS newly added to the mix, this handheld marvel has no equal,” and he offers an “enthusiastic thumbs up.”
