China Unicom Deputy Director Huang Wenliang may have inadvertently spoiled Apple's plans for a big leap in 3G performance on GSM-based iPhones in a presentation on Wednesday. Pointing out network evolution over time at Macworld Beijing, he matter-of-factly claimed that the iPhone 5 would use 21Mbps HSPA+ data that China Unicom had been adding since 2010. The Impress account of events left room open for this to be anticipatory, although China Unicom would need to have some knowledge of Apple's long-term network plans.
