Need some direction on updating my BB Q10

I don't know how to update my BlackBerry OS but I had 10.1.2-something. I've been checking on my cell phone to check for software updates. I was unsure if that checked for app updates or the actual phone updates. So I connected my phone and went to BlackBerry.com. It says there's 3 ways to check for updates and one option is to do it over the internet. I clicked on the "check for updates" (while my phone was hooked up via USB) and it said it found updates. I hit install and then it's the exact same update as I had before, except my phone is slightly slower. I live in the USA & Have T-Mobile. Not sure if that means there's no official updates yet since I heard the MR update won't be available in the USA until the "End of Summer" (Whatever that means) and Yeah... :(

Swipe down from the top - Settings - Software Updates - Check for updates.
