Changing iOS App Names / Issue

I know how to change downloaded apps' names with iFile, but for the ones such as iPod and Phone, I cannot find them (I guess that isn't really true, I have) but they aren't named exactly as seen on the phone, and when I change them, nothing happens. Yes I have resprung.
Thanks,
Jason

 

That only tells me what I have already learned... from that post. I read that when trying to learn to change the names of the store apps, such as games and such. I have the issue with Apple's stock apps.
