Older version

Would it be possible to have a downloadable older version. I have updated to current version but now wont open and quits instantly. It could be because I havent updated my IPod 4g (4.3.5) to the latest; but I am currently unable to. Thanks. Thumbjam is a great app if you love to create music, loops, beats etc.
