hello all! i just ordered a sandsik 16GB class 4 micro sd card from amazon. i just want to know if i should worry about doing anything to my phone. i am running CM7 with CWM 3.x. what procedures will i have to do so i can use my new SD card normally without my phone being all weird on me? do i have to format my card to FAT32 and flash a new recovery? if so how should i do all this? (i'm on a mac just in case)
