i want to hide some apps on my xperia and i tried several app-hiders but all of them needs mobile to be rooted. is there any way to hide apps without rooting or to change icon and name?
If you want to hide an app from drawer but continue using the app, then consider installing an alternative launcher from the play store... like go launcher, holo launcher, nova, apex, adw, launcher pro... I think all of them have the option to hide apps 
If you want to hide it and not use it then you can go to settings - all - find the app you want to hide, click on it, clear data and disable it - you might have to uninstall updates before it offers disable 
this apps changes phone menu?
You mean launcher? It changes the look of the home screens, app drawer and icons, yes.
Try it, it can't hurt 
but i like my xperia u homescreen and app drawer. is there any launcher similar as xperia homescreen and appdrawer?
im afraid i dont think so.....
( and yea i love the sony homescreen too )
Look, try a few different launchers and see if you like them.
If you don't like them, then you can only disable apps that you don't want to see in your drawer.
Other than that, there's no option to hide apps.
Even if you had root, you couldn't "hide" them in stock launcher.
Only remove them or disable them.
how to disable app?
installing third-party launchers phone will get very slow.
