iPhone 5 to have 21Mbps HSPA+ data? China Unicom says so
 

We know that Apple won't be unveiling its next superphone for a few more days, but we may have a tasty tidbit about the iPhone 5 ahead of schedule. So the story goes, China Unicom's Deputy Director Huang Wenlian was making a presentation at Macworld Asia, and stated that the new iPhone would utilize the company's HSPA+ 21Mbps network. Now, we aren't saying it's a sure thing, but it appears that Tim Cook could deliver a handset with thrice the data speeds of its predecessor next week. Fingers crossed, ya'll.
