I've notice that since the recent update to the Yahoo Weather App, my location services icon is constantly on. This is most likely a bug that will be fixed soon, but in the mean time it's unnecessarily draining the battery. I'd suggest deleting the app until it's fixed. To add insult to injury, this version also introduced ads to the app. With all the weather app options, it's hard to understand why Yahoo would clutter theirs with annoying ads, although I'm sure the answer is obviously for revenue. Not sure I'll reinstall even if the GPS bug does get fixed, which is ashame since I've used the app probably since I got my first iPhone, the 3gs.
