You can find a whole list of compatible hardwarelist at HCL ...

Maybe we can rename the link on top as "Compatible Hardware" instead?
Note that with your J720, you will be able to surf the web and access Yahoo mail, but only through its mobile mail page. That means, they will only display an email broken up into pages eventhough our handheldpc can cope with a long email!
But at least, you can get your emails.
