There is currently no way to hack this phone at all. As of right now its impossible. People are trying to work on it but are having no luck. Microsoft & Sharp has dropped this phone and are no longer supporting it.
They also will not release what we need to make the phone Open Source so anyone can hack it. At this point until someone steps in that is above who who we have righ now to Officially hack the phone I would not count on anything being done.
No offense to those who are trying but at this point I just cant see the phone being hacked
