user50365: I got an SD card breakout from an online shop, its the iteed kind without the level shifter, it has the 3.3 / 5 V switch. I cannot find any libraries or write example for it.
Has anyone dealt with it before with Arduino? I have tried finding info but I only get the level shifter kind that has the MOSI pins!

user43025: So, a quick google for "Itead SD card breakout" comes up with their website/wiki where there is a schematic.  Can't believe you did not try this.  It is just that - a breakout board.  It will allow you to connect Arduino to an SD card.  You can look up any generic example for SD + Arduino on the web.
They explicitly say 

It can work with 5V or 3.3V power supply, and both 5V/3.3V IO operation level. It can be controlled directly by a wide range of microcontrollers such as Arduino, AVR, PIC, ARM and MSP430.
