Can I deduct communications and utilities expenses under my parents name?

I live with my parents and run a business online and was wondering if I can deduct my phone bill, internet, and utilities. These bills are under their name, not mine. I do have proof of checks written to my dad but I'm not sure if since it's not in my name if I can deduct it from my business expense since I don't own the house and I just live here.

 

Thanks.

 

Also I can deduct the full price of a brand new iPhone right? I bought it for my business and do have a receipt.
