Standard feature such as immediately able to pick up a call rather than wait 4~5 secs before the phone can be answered w/o the need for overclocking the device to 1100mhz. Or when i wanted to transfer phone credit it would not let me use the special USSD or whatever it's call code from get go. Or that for the most part the phone has to be kept in landscape mode. The navigation software was pathetic with no turn by turn feature. Nokia stopped the support outrightly for the phone which was about 700+ at launch.
