可以，unlock HTC 非常容易，網上有詳細介紹

先找到MSL：

* Change the following registry entries in:
HKEY_LOCAL_MACHINE\SOFTWARE\HTC\ATDbgLog
Enable: 1
LogMode: 1
* Wait a reasonable amount of time and soft-reset。
* Check to see that the file \Temp\ATDbg0.txt has been created.
* Return the registry values back to what they were (most likely 0) waiting the same amount of time as above.
* Look in the ATDbg0.txt file and you should see a log of commands sent to the CDMA radio and there should be something like this somewhere in the file:

Code:

113 Tx:AT+HTC_RMSL=0\r
113 Rx:+HTC_RMSL: 354201\r\n0\r
113 Tx:AT+HTC_ROTKSL=0\r
113 Rx:+HTC_ROTKSL: 216112\r\n0\r

* The numbers next to the Rx: +HTC_RMSL line should be your MSL （354201）。

然後dial ##778#，用MSL code進入EPST，就可以隨意設置了。
