2 minutes worth of work with a sharp knife or file will allow you to store an extra micro SD card under your battery cover and keep it flush to the surrounding plastic.

Take off the battery cover flip it over. Look for the area slightly larger than a micro SD card with a ridge running thru it.

Using a sharp knife cut this ridge out and shave it down so that it's smooth.

Viola, you've got an extra micro SD storage area.
