Apple has released its 16 GB iPhone. With a price tag of $499, the new double-your-storage version is available immediately from both Apple and AT&T in the United States. Apple also announced a 32 GB, Wi-Fi-enabled iPod Touch for $499.

“For some users, there’s never enough memory,” said Greg Joswiak, Apple’s vice president of Worldwide iPod and iPhone Product Marketing, in a statement. “Now people can enjoy even more of their music, photos and videos on the most revolutionary mobile phone and best Wi-Fi mobile device in the world.”

The 16 GB iPhone is good news, but there is still no sign of a 3G version.
