I'm working on web forum/community software which should be compatible with just about any Web-capable device, regardless of browser.
I've dedicated a lot of time to compatibility, and now it is usable and fully feature-accessible in IE4, IE5.5, IE8, Netscape 3, 4, Opera 3-12, Lynx, w3m, Chrome 1.0, old Safari versions, etc.
I'm still working on a few IE3 issues, will be fixed soon.
It's intended for time travelers, retro-computing enthusiasts, and post-apocalyptic users with whatever device they found in the closet of the abandoned building.
It's also intended as inspiration for Web lovers of all kind to show that that it is possible.
Do you actually deliver different versions of the site depending on browser, with more and fancier features for modern browsers, or does it look the same on everything (with different CSS/JS fixes for all the horrible old browsers)?
It's largely the same version, with a couple of .js files that get included or left out depending on feature checks. This is necessary because one is a library written in modern JS with syntax like ===, which causes syntax errors in older browsers.
Please, do check it out in Windows Phone. I have only tested it once so far. It worked, but it was a while ago.
