In fact, one of the main reasons why people go for the china model is because its capable of responding to the needs of a consumer more through its features.
One such unique feature is the dual sim support. This is something you will never find in the Apple iPhone (at least none so far). For some reason Apple doesnt add this feature to their products. But its nonetheless a very useful feature for most consumers.
Shake and Tilt technology is also one of the more popular unique features of the HiPhone. Its a feature that allows you to perform media related commands (i.e. organizing photos, listening to music, and changing views) by merely shaking or tilting the phone.
Other features of the HiPhone include a removable battery for easier battery replacements as well as the detachable QWERTY keypad, to conveniently suit your preference in texting.
