Apple’s new iPhone 4 is the company’s biggest update yet for the handset and it will have you drooling.

The phone is a snazzily slim, glass-backed slab that boasts some impressive specs: dual cameras, a big operating system update and video chat, among other things.

Apple introduced the phone at its developer conference Monday and said it will be available on AT&T’s network starting June 24.

But when the iPhone 4 hits retail shelves it will have to battle a gaggle of Android devices for consumer attention — the most significant of which is the HTC Evo. The Evo has one big advantage that Apple can’t beat. It runs on Sprint’s 4G network, while the iPhone is stuck on AT&T’s 3G service. Sprint 4G, though, is not available in most major cities, including San Francisco and New York.

If you are considering upgrading to the latest version of the iPhone or getting an Android device, take a look at how the iPhone 4 and HTC Evo 4G compare:
