Hacking a phone not necessarily only for installing cracked pirated software...
Even if someone want to "tryout" some application/games before purchase,
for certain cracked applications/games won't install even if you signed it,
unless you sign it with a 20-cap cert.
Sometimes when the phone acted weird and you don't want to hard-reset it every time,
you actually have the capability to browse to the protected folders and files if the phone is hacked,
example 1: delete the "mail" folder make the phone ask you again whether to copy or move your msg to the new location (when you set from C: to E: or vice versa)
example 2: we can delete corrupted image thumbnail cache so the system will rebuild one automatically instead of continue using the corrupted one.
it is something like making changes to Windows' Registry, just like for somebody, they will gone mad if we don't have access to System Registry, C:\Windows and System32 folder etc...
like some user hack their Windows so that they can use third-party visual style (Windows theme) etc...
Another thing we need to hack the phone is to make customization or modding...
the most amazing thing people doing is the fantastic transition effect~!
I understand not everybody interested in doing the above stuffs,
this is just for certain users' interest/hobby to customize things they bought.
