This is what is new in the Lumia Denim update for the AT&T Lumia 1520
Although app and OS updates are great, what is even better is when companies post the entire changelog of what exactly is new. Luckily for us, AT&T agrees with this idea.
Earlier today, AT&T released the Lumia Denim software update for their Lumia 1520 and now the company has posted a very detailed listing of what has changed.
Most of the features in the update are already known, but things like the 578MB file size or Femtocell closed subscriber group (CSG) access being enabled are certainly unique.
