I have Sony Xperia M. It has 4GB of built-in memory, however I see only 2GB)))
The fact of applications can be installed only in built-in memory upset me very much. I do not play any hard games. Heavy one, I've installed, is 150MB program of off-line maps with 3 city and it occupies all of place((( Now I have a 16GB of free place on my SD-card and I get a message every minute, that it is not enough memory for android. It is very sad news.
I have moved or deleted from built-in memory everything I can. Can I explain to my phone that sd-memory is exactly the same memory as a built-in? Or somehow can I move one my heavy application to sd-card, keep it works? Or what do you advice me with this?
Thank you in advance.

for possible non-root solutions? I know they do exist, question is just which of them works with your device. See e.g. this answer (newer syntax), Move App to SD in Jelly Bean.
