Nokia 6061

Can anyone tell me if I can look at the spec and be able to tell if 2 handsets are equivalent in terms of running the same java app. Because I am thinkign about buying new handsets but I have some old java apps that I want to move over to the new handsets. Even better, maybe some one can give me a list of equivalences for both the Nokia 6061. hehehe~~

Thanx 😁
