Nokia Customer Service Agent here says once you have bought a N900 device in India, Which comes pre-installed version of PR 1.2 you cannot again Re-Flash to the Global Version of PR 1.2 for want of Skype Video Calling Feature, simply because all N900 devices sold in India would have a India Specific IMEI & Product Code, which would not allow the user to Flash it to the Global Version of PR 1.2. is that True ?
