Contrary to popular belief, hacking your Symbian phone is not just a sport for software pirates. Setting your copy of Symbian free allows you to install unsigned programs, customise menus and icons, clean up your active standby screen, 
switch off that annoying camera shutter sound, make backups of all sorts of things without having to use the piece of Windows-only bloatware called Ovi Suite (just as bad as the old PC Suite), and much more.
But Nokia doesn't like freedom. They especially hate your freedom to control your own phone. That's why they made firmware updates that kill the Symbian hacks to take control of your phone away from you.
Some Symbian phones can be fully hacked with the HelloOX and HelloCarbide methods (which means that you can switch off the capability restrictions completely for all programs), others can be partially hacked with the HelloOX method, but switching off capability restrictions requires additional hacks (such as ROMPatcher patches). Your hacking options depend on your phone model and firmware version.

ROMPatcher patches and other tricks designed for Nokia phones will not necessarily work on Samsung phones. Anything beyond the ability to install unsigned programs is a bonus on a hacked Samsung.
UPDATE: You can now patch installserver.exe on new firmware too, so you can install programs on new phones with new firmware without having to sign them first.

A list of Nokia phones and their firmware versions
Is your Symbian phone too new for HelloOX?
The old hacks (HelloOX, HelloCarbide etc.) don't work on the latest Symbian phones (Nokia C7, Nokia N8, etc.), and developer certificates to sign those hacks (required to install them) are almost impossible to get since 
Nokia played dirty.
The good news: you can hack new Symbian phones with S60v3, S60v5, and Symbian^3 with a 
brand new antivirus hack (preferred method) or by flashing the firmware.
