Is there a SD Tutorial?

Hi
Looking to make my sdcard to work with ADPmicroSD from www.propox.com with any library i found.
What is strange he use 4 line level shifter and looking at Data-Logger Shield for Arduino they dont use lvl shifter for all 4 line just 3 and let MISO w/o lvl shifter as long the line is IN for my Ardruino Mini Pro 5v 16mhz and as long the sdcard is powered by 3.3v the in will not go over the capability of Amtel328p.
I dont know if this make my board to dont recognize any micro sdcard i have around me (2x2G, 1x8, 1x16) all give me same answer.
I will wait to get my cheap SDcard breackboard with resistor divder (for 2usd it worth to try) and 3.3 regulator.
