Discovering specific phone model in JS

Question

I am aware that User Agent sniffing is not a fool-proof approach due to the plethora of devices that are getting released on a day-to-day basis, however I need a way to pick up the precise phone model that a user is accessing my site with in order to direct him/her to the appropriate help area/documentation.

Tools such as http://detectmobilebrowsers.com/ allow you to detect the mobile device, browser, os etc but is there anything that can pick up the specific phone model you are using (using Javascript)? E.g iPhone 4s

Thanks for any ideas.
