Since upgrading I have been getting much faster downstream speeds in the Washington DC market in which I live. We have had verizon AWS spectrum for quite some time But since upgrading to 8.4 I have been getting speeds upwards of 70mbps during the middle of the day which used to be unheard of unless I was doing a speeded in the middle of the night when no one was using the base station. I noticed the carrier version got bumped to 19.6 from version 19.0 in the gm of iOS 8.3. Has anyone else noticed these improvements in a market where Verizon has both let and xlte(AWS)?!
