[Q] Is possible to make a sd virtual partition? topic

Hi,
I have a htc one x for a day and I don't know all the peculiarities of this device. I have read that's not possible to make an sd card partition to move some apps to it. Someone said that would be possible to make an image inside sd card and mount it but I cant find anything more about this approach.
I guess should be a way to do that becuase the /data space isn't enough. And I ask you what can I do to get more space to install apps on this device?
