It looks like Jott is a very popular program that it wants to be used on other systems. On their forum people are saying that they will _____ for their G1 phone android(?) and that they would like to see if other phones but it looks like that's not gonna happen. The administrator said that their suggestion is good but they only develop it for a popular request and popular things and I don't blame them because it does cost money. So, hopeully Jott will be develop for other systems.
