I used to work with Iphones quite a bit shipping them overseas. You can't bypass the Icloud activation lock no matter what anyone says.
If you want to actually use the phone you will need the original e-mail information, and if you contact Apple they will likely require a proof of purchase.
Apple employed this Icloud lock to stop wholesalers from buying and selling Iphones. When they would get Icloud locked phones, they were forced to be sold for parts and customers would have to purchase new.
While you may not be able to bypass the Icloud locks, you can still sell the Apple products for parts... which are worth more than you might think.
You can get 60-70% of what the product would be worth fully functioning in used condition.
