There are different rules about what is permitted in carry-on and what is permitted in checked luggage. Here
is a page saying what's allowed and not allowed in carry-on and in checked. You're allowed shampoo and conditioner in your checked luggage. You're even allowed it in your carry-on, so long as it's no more than 100ml.
I haven't flown for a while, so not sure about the phone and iPod thing. I'm pretty sure you're not allowed to use a mobile phone but, who knows, things may have changed.
