BEIJING-BASED DARE&SURE LAW FIRM has brought the first anti-monopoly case against Apple in China. Beijing-based newspaper The Mirror comments:

The iOS operating system Apple installs on its products such as iPhone and iPad is a closed-source one and its users have no other channel but the virtual Apple store to download and install applications.

Such a technological barrier is jokingly known as "jail" among iPhone and iPad users. There used to be a group of hackers who developed special software to help users "jailbreak" iPhones and iPads, but Apple has defeated most of them by closing in the loopholes in the iOS operating system.
