Samsung MM-A700 / SPH-A700
Invalid URL: Samsung A700 Problems with URLs
When browsing WML pages, the Samsung will REFUSE to load any url that contains square brackets, [ and ]. They are not illegal in URLs to my knowledge, and are heavily used by the PHP community to pass arrays of values back and forth on pages.
Why Samsung refuses to load pages with square brackets, I know not, but it does.
Hope this helps someone.
