provides this sort of information for Nokia phones in its device table
. Other manufacturers probably have similar information available.
Forum Nokia's device table confusingly has two kinds of information: individual pages for some devices from the 'Select a Device' drop-down menu, and then a table with information for pretty much every device which you access using the 'Series 40', 'Series 60', 'Series 90', 'GSM', 'CDMA', 'TDMA' and 'W-CDMA' links. The info you want is in the table entries, not in the individual pages.
