Why does my iPhone 4s say it only holds 28.22 GB?

Why does my iPhone 4s say it only holds 28.22 GB

It says it was 32 gbs right? Ok so what happens is like all the apps that are already on it (camera, calendar, calculator, etc. ) take up space. So I guess apple is kinda jipping us all in the long run. Haha hope I helped

Some of the memory is used by the programs that are built into the phone. Then ther is the things you add, apps, contacts, music, games, etc.

There's already some software that takes up some of the space in a 32 gb, like my 16 gb iphone says about 13.8 more or less gb left after all the software takes place
