Even the 4G toggle works (coupled with LTE on/off app. Didn't test without LTE app). Not a battery hog and a lot of options for customizing. You'll dig it, trust me. GPS option is semi weird, I'll admit, for it brings up location settings as opposed to just toggling GPS on/off. Minor compared to how good this app is.
