问题：我有一部手机，我如何能确定我的手机是世界上唯一的？
补充：
1、如果你告诉我用IEMI码来识别，那么请告诉我如何能保证IEMI码不被别人修改。
2、如果你告诉我用手机号来识别，那么请告诉我如何用代码读取到手机号(模拟器我也能读出来，我需要的是真机)。
3、如果你有其他方法，那就太好了，我就需要其他方案。
------解决方案--------------------
windows mobile 上面有个unique id ,是根据app的guid和硬件的一些属性运算得来的
HRESULT GetDeviceUniqueID(
LPBYTE pbApplicationData,
DWORD cbApplictionData,
DWORD dwDeviceIDVersion,
LPBYTE pbDeviceIDOutput,
DWORD *pcbDeviceIDOutput
);
不知道离你的要求还远不远
