Apple introduced models of its popular iPod touch handheld computer and iPhone with double the memory available in previous versions.
Apple, which said in January it had sold more than 4 million iPhones since sales began last June, says the iPhone will now also sell with 16 gigabytes of memory.
The iPod touch, a wireless touch-screen device that plays music and videos, adds a 32 gigabyte model. Both devices will sell for $499, Apple said.
