[Verizon Samsung Galaxy S III] TrevE:
I have seen some questions posted about version numbers of APKs that show up in Settings. Over the last few hours I have used my processing power to making sure r420 is up to 4.1.2 correctly. Below is full report in the interest of being open.

Starting with framework, all changes check out 100% to the 4.1.2 framework for the updates we wanted to take. Some 4.1.1 -> 4.1.2 stuff we did not want, such as CityID crap. We have also opted to keep our 4.1.1 framework-res.apk and just realigned the new framework to work with our older framework-res. This allows SynergyRom to keep a unique compatibility with 4.1.1 stuff, and makes themers lives a bit easier.

As for applications, I have checked everything again to the 4.1.2 OTA. Some of the APK versions in a stock deodexed 4.1.2 rom I downloaded have older versions then the 4.1.1 OTA (see kies, phonesky, etc), so we elected not to take those.

You can see a list of every system APK version in Synergy r420 up here - http://pastebin.com/raw.php?i=eN3D8bQN

From the full check I ran:

1 apk is at 4.0.4

--Microbes.apk - Microbes Live Wallpaper. It was removed from future OTAs and will not be updated.

6 apks are at 4.1.1

--CSC.apk

--HiddenMenu.apk

--SecLauncher2.apk

--SecPhone.apk

--SecSettings.apk

--SystemUI.apk

Out of those 6 APKs on 4.1.1, here are the changes we are currently "missing" from not using 4.1.2 apks.

CSC.apk

New Sim profile for "DCM" sales code

HiddenMenu.apk

Remove CPU key of "MSM8960" from BSR

Change EHRPD_View for salescode none and CRI

Check additional permissions for writing PRLs to "SCH-S960L" or SPR sales code

SecLauncher2.apk

Change way progress bars are displayed when notifications are in compact mode*

Remove or Change maybe shake animation from delete icon?

SecPhone.apk

Removes support for "emergency_tone_alert_always" & "emergency_tone_alert_master_vol"

SecSettings.apk

SystemUI.apk

Changes the way Expandable List gestures are called

Changes the way the Clock is Displayed

Support for DCM salescode (?)

Changes the way 4g vs H data icon is displayed

Brightness levels in call when in powersaving mode

As you can see there are not many real changes in these apps by using the 4.1.1 versions. Just like framework some of these 4.1.2 things we do not even want in our ROM. So feel comfortable you are not missing out on anything by having 6 older apks, the changes we did to most of these are more noticeable than any of these new 4.1.2 "changes"

Regardless though, for next build we have 5 out of the 6 already upgraded with certain features removed or tweaked/Synergized for whenever we drop a quick release :)
