I did a search and didn't find the exact answer I was looking for...sorry if it's already been discussed. I currently have a Droid2...and upgrade time is coming up in a few months and I am going to consider the Droid4, which is a 4G phone. Since 4G generally drains the battery pretty quick, and if that is the case on the Droid4, would it be possible to just use the 3G network instead of 4G? In short, can 4G phones be set to just use the 3G network to save on battery life and whatnot? I assumed so since if you are not in a 4G area, it will run on 3G...but just wanted to make sure it was available as an option. Thanks!
