Can the now expired iMessage app still work with Lion? I want to use iMessage on an old Macbook which cannot be upgrades past OS X 10.7.  Apple provided an iMessage beta software, but it has expired and no longer functions. I'm wondering whether there is any way to keep using the iMessage service on the Lion OS?
No one has come forth with a hack or modification to get it working. The longer it takes, the less likely someone will want to release a patch since the audience for this shrinks as people upgrade and move on to Mountain Lion.
