Subject: Re: China bans Iphones for government employees
"China ordered officials at central government agencies not to use Apple's iPhones and other foreign-branded devices for work or bring them into the office, the Wall Street Journal reported on Wednesday, citing people familiar with the matter."

Backend servers can intercept all messaging, track locations. There're reports that EU leaders' phone calls were monitored by the US. Pretty soon, it won't be just China government that bans the iPhone.
