Remove your memory card, if it stops freezing, the card's your problem. Either the card is not compatible (more than 4gb or SDHC instead of SD), or the phone is referring to the card during normal operations eg wallpaper, ringtones etc. Copy these "operational" files to the phone and only use the card for storage of pictures, music etc, but not for anything the phone uses regularly. If the problem persists after you've taken the card out, sorry can't help...
