I was just wondering if there was something else I needed to do other than just downloading and installing.
first, get "root explorer"
for system apps like those, you have to delete them first in root explorer
go to /system/app and long press on the apk you want to delete, and choose delete
if you have a recovery that allows you to wipe cache, now do that
then, assuming you've already copied the new .apk files you want to install over to your sdcard, go to /sdcard, and "move" them over to the /system/app folder
then, long press the one you want to install, and fix permissions on it to rw-r--r--
(in other words, when the dialog box with the permissions check boxes comes up, only check the following: in the user line, only check "read" and "write"
in the group line, only check "read"
and in the others line, only check "read", hence the rw-r--r-- permissions)
then reboot, it should then be installed
there's other ways to do this, like adb, or even terminal emulator, but this way you can do it on the phone itself, without the use of a computer, and without typing any code
