According to a Reuters report citing an unnamed analyst's source, China Unicom is expected to announce tomorrow that it will be selling Apple's iPhone in the country. A China Unicom spokeswoman would not confirm the deal, but said that the iPhone would undoubtedly be discussed Friday when Unicom holds a media briefing to discuss its first-half results.
