iPhone 5 will support HSPA+ 4G technology
During a presentation at Macworld Asia, China Unicom revealed that, as long and widely rumored, iPhone 5 will support HSPA+ networks.
Japanese IT news site "PC Watch" tells that, Research vice president of China Unicom, Huan Wenliang, told iPhone 5 will support W-CDMA based high-speed data transfer standard HSPA Evolution "HSPA+" (21Mbps) at keynote speech in Macworld Asia 2011.
While HSPA+ is really a 3.5G technology, T-Mobile, AT&T, and now many other carriers have been marketing it as 4G for a while now in order to compete with real 4G networks like Verizon LTE. (Turns out it's easier to print 4G on a box than build out an actual LTE network, go figure?)
It will be interesting to see how an HSPA+ iPhone will be marketed by AT&T. Will Apple let them call it a 4G iPhone?
