M-x py-shell 

will get you a new (I)Python shell.

This works for me in the sense that I get history from emacs (via comint) rather than IPython's history, which works pretty well.  It sounds to me as if comint (which is responsible for running IPython) is picking up your bash shell history. In fact if I have a running IPython shell and then start a new zsh with M-x shell, type a couple of shell commands to the shell and then use M-p to get the history,  I get the shell commands and followed by my most recent IPython commands and switching buffers to IPython and using M-p gives me the shell commands and then the IPython history.  It looks to me as if you might do something like what's on the emacswiki: http://www.emacswiki.org/emacs/UsingMultipleShells , but I'm afraid I haven't time right now to try it.
