There are some interesting articles in vol 1 issue 4 (2005) of the online journal International Journal of Education and Development using Information and Communication Technology
at http://ijedict.dec.uwi.edu/index.php, including
Martin, B. "The Information Society and the Digital Divide: some North-South comparisons." (which I skimmed through and found useful summaries of the situation and thoughtful discussion).
Macleod, H.J. "What role can educational multimedia play in narrowing the digital divide?" (highlights the value of multimedia e.g. in cultures which put more emphasis on oral traditions).
