I think you are mistaken.


Best practices has the concept of Default Delivery Context, i.e. minimal 
set of features which guarantees that a mobileOK will be displayed 
correctly. These properties characterize your typical feature phone:

Usable Screen Width

120 pixels, minimum.
Markup Language Support

XHTML Basic 1.1 [XHTML-Basic] delivered with content type 
Character Encoding

UTF-8 [UTF-8].
Image Format Support


GIF 89a.
Maximum Total Page Weight

20 kilobytes.

256 Colors, minimum.
Style Sheet Support

CSS Level 1 [CSS]. In addition, CSS Level 2 [CSS2] @media rule together 
with the handheld and all media types (see CSS 2 Media Types).

HTTP/1.0 [HTTP1.0] or more recent [HTTP1.1].

No support for client side scripting.

Again: a MobileOK page is supposed to work on a device with these 
minimal features.
