Also dont forget that if you do manage to move a chunk of data (pics etc) on to the SD card it may not be required to move ALL apps anyway and those left may well running perfectly well, using small amounts of memory on your phone just. Also ( and just to point out the obvious I know) but have you checked on your usage of all your Apps as if you're anything like me / most people you probably have several ( many) apps installed that are rarely used but taking up precious space and if so just delete the entire App and be done with it to gain a little space back too.

I'm assuming you've already set all your pics ( and music / media file / books PORN :-) etc ?) etc to "save to your SD card" as that too frees up a mountain of space.

Sorry the above doesn't directly answer your question BTW as Moses reply I presume helped cover that, but just thought me little bit of info may help too a bit more,
