Be very careful if upgrading to KitKat 4.4.4. It is very buggy, broke Exchange support for me, which is a big problem. After searching online it looks like this is a known issue.
So if flashing a ROM, check if it is AOSP 4.4.4 based and if it is I'd recommend searching for any known issues before flashing.
I found issues with it a a well even though it was supposed to be a bug fix release. 4.4.3 had a security issue also so I'm not sure what to stick with haha.
