"1) Simply put the *.zip file with the regeditSTG.exe in it with ActiveSync into a folder on your phone (but not onto the memory card).
2) Unzip the file with the *.zip program that comes with your phone.
3) Now start regeditSTG.exe and change the following Registry Keys:
HKEY_LOCAL_MACHINE\Security\Policies\Policies0001001 = 2
-> Change the value data from 2 to 1
HKEY_LOCAL_MACHINE\Security\Policies\Policies0001005 = 16
-> Change the value data from 16 to 40
HKEY_LOCAL_MACHINE\Security\Policies\Policies0001017 = 128
-> Change the value data from 128 to 144
-> Add new value "0000101b": Dword = 1
After you have done all these steps close Regedit STG with the task manager (TaskMan) of your phone and reboot. That’s it.
Your phone is now totally application unlocked." robertpeloschek.blogspot.com
