I was fiddling with my phone, and tapped on the "Software Update", and to my surprise there was an update, 19+ MB in size. I let it do it thing.
I am not sure what got updated. Anyone?
It really depends who your provider is. I had a small update come through on May 20th
82,39MB Notes state it's to "Improve Stability"
I am with Telus is Canada though. So again, depends on the provider.
