Not much to add here that wasn’t in the headline. The Verizon Droid DNA is getting an update today to software version 710RD for what Verizon says is “improvements … to SIM card detection.” And that’s it. So if SIM card detection is a feature you find important (and we’re willing to bet you do), snag this update as soon as you get a free minute.
