Is it a good idea to show product info again (product image, colour, size, quantity) in the 3rd step of checkout (Step 1- shipping, step 2- billing, step 3- order review and placement) on the mobile device, considering the fact that checkout funnel starts with cart page, which means all the users first see their cart (where all the products with full details are shown) and from there only can proceed to checkout.

I am working on the checkout flow for the mobile device, and it has 3 steps, Step 1- shipping details, step 2- payment details, step 3- order summary and confirm to buy. The flow starts with cart page where user can see product info, edit it, apply coupon code etc and from here can proceed to checkout. Is it a good idea to show product info again (product image, colour, size, quantity) in the 3rd step of checkout considering the fact that checkout funnel starts with cart page where all the products with full details are shown. I am wondering if the summary page would be overwhelming with too much information to digest thus defeating the purpose of the step? Suggestions?
