I have noticed that the browser on my Motorola E815 doesn't handle large web pages well. Usually an out of memory error would occur, especially when there are large images. So I wanted to find a proxy that would format web pages for the phone.
One of proxies that I found is PHONifier. This is a simple php script that makes web pages simpler for displaying on the phone. Unfortunately, it doesn't resize images, it does have an option to block all images.
