Update (31-7-12): New version. It checks the hostfile now, and removes the accuweather host from it if necessary. Works great with AdFree and AdAway. Also, to better work with the clock application in sense 4, the geographic position of a city is added to the database. It will search for the coordinates automatically, but you can also manually add them. Enjoy!

Update (16-7-12): Problem occurs on devices having an addblocker that changes the host file (/etc/hosts) installed, like AdAway or AdFree. They add the line "127.0.0.1 netweather.accuweather.com" to /etc/hosts, removing that line or changing back to stock host file solves the issue. See this post for more details.

Update: There seems to be a problem with the server the app connects to, it is not accessible from some (many?) countries or phones. I haven't found a solution yet.
Please try this link with your internet connection (so wifi or mobile), if you get a xml file back, this app should work. If it doesn't, but you can access the site above, please let me know.

Please let me know if it works as well, as well as your country, so I can try to figure out what's going on.

Update (7-7-12): You now have the possibility to manually add a city through its location code.
