Seems to work properly, I have received an old message and sent few.
Though the dots are acting weird. In "Chats" it's red dot and when in Chat-window i's green.. Sent or not sent?

Also it needed a few reboots to work. Could be my carriers (saunalahti, Finland) fault also. 3G's been quite sluggish for few days.

Awesome job. You saved my day!

.. but my N900 could use this app too. AND FAST!

AND SUDDENLY! I received a new message while writing this. Seems to work.
