I've a 4GB SD Card installed in my Xperia Ray ST18i. Now I've purchased a 8GB Card to replace the 4GB one. Being the internal memory very less and as I use many applications, I've moved almost all of my apps to SD Card and still left with just 50MB of free space in Phone Memory. Now, what I wonder is while changing the SD card, do I need to move back all the apps to Phone Memory (which would not be possible as the free space left is only 50MB approx). Else, just copy pasting all the content from old card to new card would do? Kindly suggest me the way around. Thanks in advance.
