I just released a new version of Wallpaper (with the help of socketface) that should take care of the problems on the 1.1.3 and 1.1.4 firmware. Let me know if it works! There’s more coming - I just can’t talk about it yet. 
Ok folks, I know a lot of you want Wallpaper to work for 1.1.3. Unfortunately I think it’s going to have to change slightly since the app can no longer write to the system wallpaper directory and a few other places. The reason is mostly because 1.1.3 runs the applications as a different UNIX user which does not have write access to those parts of the filesystem anymore. I’m thinking about what to do about it. It might mean that rather than putting wallpapers into the system, I’ll have to write a wallpaper browser so you can save good ones and access them from within the Wallpaper app itself.
There are a few common requests for improvements to my iApp-a-Day apps that I see over and over again - one of the more popular ones has been a desire for a feature to save images from Wallpaper to the system’s Wallpaper folder so they show up in the phone/ipod Settings menu. (Especially useful for the poor iPod Touch users who don’t have a photo roll.) Well rest easy, folks - I have finally got around to adding that very feature! Enjoy.
Update: Fun stat.. in 24 hours, the new version was downloaded about 17,000 times. Also of note is that there have been 249,742 wallpaper uploads this month so far. (Not all unique - basically this is the number of times the Wallpaper app was started so far this month since each time it starts it uploads your wallpaper image.)
Update 2: If I correctly did the math on this, these numbers mean that someone in the world starts up Wallpaper approximately every 6.2 seconds! Amazing!
I just found out about a neat Javascript-based programming system for the iPhone called Jiggy. It’s probably a coincidence, but a few years ago I started a project named JiggleScript which happened to also be a Javascript-based development system that I had grand plans for extending with modules and such. (But since I can never seem to find anyone to help me with my projects, it of course died when I got bored of it one day.) The Jiggy team has a pretty extensive thank you page and JiggleScript isn’t mentioned, so it’s probably just a weird, cosmic case of… something.
Still, though… the universe is bizarre, isn’t it? I wish the Jiggy folks the best of luck - it looks really cool and targeting the iPhone with something like this is pure genius of the forehead-smacking variety. The iPhone platform is exactly the sort of thing I desperately wished for back when I was playing with JiggleScript (I even had ideas for a browser-based IDE like they are doing!) and when I got an iPhone and started developing for it, I never once thought of that old idea - instead I took on a much more exhausting task that, while I know has been helpful to many new developers and entertaining for others, is likely to have nowhere near the staying power or ultimate impact that Jiggy will probably have.
