Hello! So I used to have a MyTouch 3G Slide and I was always able to turn on my GPS, then update my city in the weather app, and then turn off my GPS. Now, with the 4G Slide, whenever I turn off the GPS, the app still won't load my current city. I really don't want the GPS to be updating constantly when I'm out. It's going to drain my battery! Does anyone else have this problem or know how to fix it? Thanks!
