Stock MMS app for non-stock KitKat topic

Hi,

I just replaced my nexus 5 for a galaxy note 3 but I basically prefer stock google apps so I'm replacing samsung apps for stock ones when possible, first things first I wanted the stock MMS app back cause I don't like hangouts too,
as samsung is naming their apps the same name as google it's hard installing stock ones without root (and removing the samsung version first), as a solution I renamed the app so it can be installed without conflicting with samsung app

basically here's what I did :

- extracted the MMS app from the Android SDK image
- deodexed
- decompiled
- renamed all occurences of com.android.mms to com.android.stockmms
- renamed all occurences of com/android/mms com/android/stockmms (in smali stuff)
- renamed occurences of mms_temp_file to stockmms_temp_file
- recompiled

I tried the same on contacts (people) app but there's a problem with a shared certificate with android.uid.shared and the app will not sync with user account contacts or something

Here's the mms apk (4.4.2-938007):
