Thank you for your response ViBE: very comprehensive. Sadly I've found that my N9 has a dead strip in its touchscreen (can't press U,J,N keys on keyboard) so it's being sent back. I'll have to wait for a refund/replacement before I can put the above advice into action.


To chilango: I know that I can't change the CMT portion of the Chinese firmware, but the rest can be replaced, as described in this thread.
