This is definitely a software issue
(the unresponsive buttons "respond" when performing a hard reset...) Also, with my keyboard out, I can get the buttons to work but only after pushing the "blue dot" (bottom left corner of keypad.)
So, the buttons definitely work. (Currently using wheel as camera button...) I've read something about returning to original rom to fix. Has anyone tried it, and if so...does it work?
Thanks!
