There is no way that you could port the shoddy battle code to the iPhone, so it would have to be written from the ground up. It will be a lot more feasible to do with shoddy battle 2, since the networking and team formats are a lot simpler.
I might start doing some iPhone programming myself so there is a remote chance of it happening, but it's a fair bit of work for not too many people. There's also the $99 entry fee to release apps. As Obi said though, anyone is free to make an app if they are capable.
