I want to create a mobile site and want to target almost all devices from High end (Iphone,android) to low end (nokia's, LG Flip-phones).
Which method to choose for dvelopment:
Developing 2 sites one built on HTML5 for targeting latest handsets and second built on XHTML MP for supporting old handsets also.
Using Mobile boilerplate - developing site on HTML5 and including fallback script (with the help of modernizr) for handsets which does not support certain HTML5 features.
Which method seems convenient and sensible.
