Symbian platform security hacked again !!

Looks like the hackers arn't giving up so easily yet !! The new hack from Deltafox over at symbian freak lets you unlock your nopkia phone from the shackles of symbian signing .
The hack has been confirmed to work on the following phones/firmware.

Nokia N82 firmware version 30.0.019 and 31.0.016
Nokia N95 firmware version 31.0.017
Nokia N95 8GB firmware version 31.0.015
Nokia E90 Communicator version 300.34.84
Nokia E71 firmware versions 110.07.127 and 200.21.188

The procedure :

1. Check if you can hack your phone with the HelloCarbide and ROMPatcher method. If you can, use that method instead. Only use the method below if nothing else works.

2. Get a developer certificate. Be patient, it can take a while before your certificate is ready.

3. Download this package from Mobile Castle.

4. BACK UP YOUR PHONE MEMORY! On some phones you'll need to click "Memory" in the settings folder, on other phones you can back up your phone memory from the options menu in the file manager. You can also back up your phone memory with PC Suite.

5. Sign MapDrives (which you downloaded in step 3) with the certificate you got in step 2, and install the signed copy of MapDrives on your phone.

6. Copy MapDrives.txt to your memory card (E:\), so you'll get E:\MapDrives.txt.

7. Install JBak TaskMan, start it, press the # key, highlight the MapDrives entry, click "options," "program rules," and select "autostart."

8. Restart your phone.

9. Delete MapDrives and install MapDrive_JBakTM_EMU_Y (for N82, N95, N95-8GB, and other phones that have a drive called Y:\), and start it.

10. Install Modo, and use the Modo file manager to copy installserver.exe to C:\sys\bin.

11. Once the modified installserver.exe is copied to C:\sys\bin you don't need MapDrives and JBak anymore, but you still need Modo to write to C:\sys.

Note: with this hack you can not write to C:\sys and other system folders with file managers like X-plore or ActiveFile. You can read C:\sys\bin with these file managers, but you can only write to C:\sys\bin with Modo.

Confirmed to work on these phones and firmware versions:

Nokia N82 firmware version 30.0.019 and 31.0.016
