Some japanese games have seen iOS releases lately, such as Final Fantasy 1/2 and Soul Calibur 1. HTC does however use Windows Mobile or Android as their operating systems, and both of these are considerably more open than iOS. iPhone customers also buy more applications on average, even if the Android install base is larger, this may partly be because the Android OS is easier to pirate on. It is not hard to jailbreak iOS in order to use pirated applications either, but on android you don't even need to do this. You can just download the app on your PC, and transfer the executable to your phone via USB and it'll usually work.
