On big red, the update is similar. bringing in Sense 6.0 and the other things mentioned above. You guys will also have some W-Fi connectivity issues resolved, ISIS Wallet payments working and Emergency Alerts preloaded. For you guys, you will be looking for version number 4.10.605.3 with a baseband of 1.13.41.0421.
As for both carriers updates, you can expect it to roll out in stages and take a little time to every device out there. You can head into Settings > Phone updates > Check for updates to see if it ready for you. If it is, be sure you have  over 50% battery life, a solid Wi-Fi connection and a little time to download and install it.
