As someone with vision issues I typically need to zoom on every single page I load on my iPhone.
The "three finger tap" to zoom kinda sucks, so pinch to zoom works great. However since upgrading to iPhone 4S I've noticed a lot of sites don't allow it.
I know there's a meta tag you can use to disable that feature, but is there an override that you can set to be able to zoom on every page? I can't zoom in on google results, so I can't really see them. NFL.com doesn't allow pinch to zoom either.
