why there is need to hack symbian

WHAT IS SYMBIAN HACKING?
Hacking will disable the security of your phone, so the phone will not check if an app is signed or unsigned while installing it.
You will also be able to see all the folders/files in your phone using an explorer like X-Plore.
NOTE: FOR THE OPTIMIST USERS ONLY .
Unfortunally you will not find any new settings or functions in your phone.
Symbian had changed almost everything on the phones software,
making it impossible to install applications that were developed for the older operating systems.

WANT TO HACK MY PHONEWHY DO I NEED A CERTIFICATE?
Because you have to use an application to hack your phone that is unsigned.
After you signed and installed this application you dont have to worry about unsigned applications anymore.
you can install any application now without signing it.
WHAT ABOUT VIRUSES?
That's a good question.After the hack thephone is trully open for everything. so in the theory we can install viruses also.
First of all hacking your phone is not hardaware depended.
you just install an application into your phone that is by the way tested on many phones without coming in conflict with the Operating System.
