We can go for whatever option suits you best, but changing the firmware is not a complicated thing. You need a programmer like indicated by me or Mike in this topic, and the software. This takes max. 10minutes . Shipping it back and forth will take 1-2 months.
EDIT: Btw, I am writing an article on the blog to provide some instructions on how to update the firmware. Photos and step-by-step instructions, it should be ready the next few hours.
