Yeah you can install even though it is burnt into the rom. Thats what I did at first. There is an oem for the new HTC Home plug for the next time you cook one. When I had the old HTC Home I couldnt get the weather. With the new one and HTC Home Customizer it works and you can make a custom city list with the customizer. It just asks you for the name etc. then the zip code. Then it shows right up.
One other thing if you dont have a data plan turn off the auto update so you dont get ridiculous data charges. Plus the customizer lets you change the clock, icons, weather icons, plus a whole bunch of other stuff.
Heres the OEM its under post #8
