How to tell the difference between BG3.0 and BG4.0?

Nickiechan

I purchased my first Cloth Diaper a bumGenius 4.0 snap. While I was out this weekend shopping at the consignment store they had a bumGenius that looked exactly like my for $6, but in aplix! So I picked it up. The RN numbers on them are the same. It was missing the newborn insert, but I know you can buy those online pretty cheaply. How can you tell difference between the BG3.0 and the BG4.0?
