The Euro version of the Nokia E71 recieved a firmware update a few weeks ago, bringing the device up to v110.07.127, but at that time, the NAM version, with US 3G, was left out in the cold. I'm pleased to let you know, however, that the E71-2 NAM has now received this firmware update, through Nokia's Software Updater application.
The new firmware is the same version that the Euro one received, which also tells us that the changelog is going to be the same. There are new versions of Nokia Email, Nokia Maps, and Mail 4 Exchange, as well as a few bugfixes here and there.
It should be noted that this new firmware eliminates the ability for you to 'hack' your phone, using the process we described earlier here at E71Blog.com. If you're using MagicKey, you may want to hold off for a bit, or look into Smartphoneware's Tracker application. Also, the Nokia E71 does *not* have UDP (User Data Preservation), so it's suggested that you backup any important information before applying the update.
