You can try installing ROM MANAGER from the play store. There is an option to PARTITION YOUR SD CARD. Just search how to do that, there are a lot of links. Once you have successfully partitioned your SD card, install Link2SD from the play store. Again just search how to use Link2SD once you have partitioned your SD card. (I had to 'Create Links' as opposed to 'Move to SD')
I went from not having enough memory to open my gallery to look at pictures to having 646mb free.
PS. Make sure you have a custom recovery, and make sure you dont mind if your SD card eventually fries. From what I hear partitioning is not the best thing for it...
Best of luck
