I ran across this lockscreen theme called wĕdaPanel over at the ModMyi forums in
I love the look of this theme as I like my weather updates. There are several pages you can
access from your lockscreen which provide information on today's weather, a forecast for the week,
the phases of the moon, and can also link to animated weather maps for any area you program!
WĕdaPanel was originally written for 3.x firmware, but has been updated to work on iOS 4, and the graphics upscale pretty well I think. The developer stated they are working on creating higher quality graphics for iPhone 4 users. This tutorial will use an iPhone 4. You will also need SSH to upload the theme, and a text editor like BBEdit to alter the html file to reflect the locations you'd like to see weather reported from.
Note: If you are somewhere that does not offer Wi-Fi or data reception, this theme will not load and you'll only see the wĕdaPanel logo on your lockscreen.
To the right, I have highlighted in blue, all the lines that you can change easily, to configure
the wĕdaPanel. First you'll notice five cities. They also have codes next to their names.
If you live in the United States, then you can simply place your zip code here. You can also customize the way your city name appears by editing the name in quotes. If you are outside of the United States, then you need to go here to obtain the code for the locations that you want weather reports for.
Refresh interval is the next line I have highlighted. It's set to 20 minutes by default. I imagine this could eat up your data allotment quickly, so you might want to set the interval higher if this is a cause for concern. The value is in minutes, so if you want an hour and a half interval between updates, then enter 90 here.
Units is next. Select imperial or metric to change between Fahrenheit and Celsius.
Clock is next. Select either 12 or 24 hour.
Theme index will change the style of icons used. Simply pick the number related to the icon set and enter it.
URLs for weather images is the final section to change. I believe this theme only accepts gifs or jpgs as input. Where you find these images is up to you. If you know a weather site that has a consistent name for your area for their animated gif maps, then enter that URL here and you'll always be up to date. You could also just set static images here if you'd like.
Don't forget to save this file once you have finished editing it!.
