∞ iPhone 5 to support HSPA+ '4G'

Mac Rumors:

Japanese blog Macotakara reports (via MacPost) that a China Unicom executive apparently confirmed during a presentation at this week’s Macworld Asia that the “iPhone 5″ set to be announced next week will indeed support HSPA+ sometimes-called “4G” technology, offering a maximum theoretical data speed of 21 Mbps (up from 7.2Mbps). A slide showing the information was photographed by Japanese site PC Watch.

That’s quite a slide for China Unicom to show a week before Apple’s launch.
