Many thanks to Finn Kraft(KillingTheEngine).
I'm using LockStatusHide to hide the status bar. It should still be available in cydia
I'll try to get a iphone 4/s version up however it'll take some time
Copied from the source: How do I change my location?
Go to weather.com, enter your city or ZIP-code in the search bar and copy the alphanumeric code from the link behind your city name.
Then open the LockBackground.html with a text editor of your choice (Text Wrangler is nice) or using iFile on your device and replace the weather behind "var locale" with your copied code.
Put the LockBackground.html back onto your device (replace the file) or just save it (when using iFile), respring and you should be done!
If you're having trouble:
According to ~Silvelix you just need to get your weather code from here and then follow the tutorial above
A little glitch for US-users:
Replace the numbers in
var locale = "USCA0819" to your ZIP code.
