The app for the clock and weather that is on my homepage changes its location at will and I can't get rid of the wrong city and back to where I am.
Let me guess it happens when your at home the most and let me take a wild guess to say that you also have an airave because of poor signal at your home? if this is the case call airave support and tell them that you need the airvana because it supports 3g the airave only supports 1xrt and that is why you have problems not displaying your correct city.
It's a known issue/Bug introduced in the last update, Should be fixed in a future update. A reboot will sometimes get the correct location. You can also tap the clock>World Clock>Menu>Automatic(UNCHECK)
