Persuading skills for iPhone?
My dad has an IPhone 5 at the moment and he is on a contract. I however have a little Samsung Galaxy Ace which is very close to breaking. I have about £100 in savings and I want to buy it off my dad. He is reasonable and he hardly knows how to use it like a proper IPhone 5 owner. I'm very responsible (I didn't break my phone) and can look after it. How do I persuade? I tried by saying I'll do extra stuff around the house, on my best behaviour and not being rude to my siblings. How else do I persuade him?
