Keith Goldrick has released a new app for the PSP, heres the details from the readme:
I started this little project just for my own personal use. Then I realized how often I used it and how others might enjoy it as well. So with a few days of typing I managed to include every region in the U.S. If you are only interested in your local weather
you can bookmark the html file that links you directly to your region.
Instructions
works on all versions- 1.0
and 1.5 needs Devhook or Links2
Copy the 'w' folder into x/PSP/COMMON
folder on your PSP.
(where x is your psp drive letter)
Start your browser and set a bookmark
to... file:/psp/common/w/s.html
