Update : IPython for MeeGo Harmattan is now released (14/11/2011).
The Maemo 4 and MeeGo Harmattan versions of SymPy do not yet use iPython, instead the simpler Python shell. On Maemo 4 because iPython 0.8 is too old and incompatible with SymPy (isympy script). On MeeGo Harmattan because there is not yet a iPython package available.
Advantages of iPython shell, which is called by isympy or the icon of "SymPy" on Maemo 5 :
- tab (or ctrl+i) completion for objects;
- input history navigation using up and down arrows;
- search input history by typing partial input then up/down arrow to show matching lines, or ctrl+r to have a serch prompt;
- input line n can be retrieved using '_in', 'In[n]', '_ih[n]', and _i, _ii, _iii to access the previous, next previous and next-next previous inputs;
- output line n can be retrieved using '_n', 'Out[n]', '_oh[n]', and _, __, ___ access the previous, next previous and next-next previous outputs;
- information about objects using '?word' or 'word?', full information with '??word' or 'word??';
- magic command system, like '%run file.py', '%pwd';
- run system commands with '!' as prefix, e.g., '!ls".

I am working to make iPython 0.10.2 available to Maemo 4 & 5 and iPython 0.10.2 or 0.11 to MeeGo Harmattan. So SymPy could also use iPython shell on Maemo 4 and MeeGo Harmattan.
