looking for information...

HI! I was wondering if there was a way to look up your purchase history on your cellphone? There are charges on my debit card for apple itunes and I don't remember what they were all for. My dad wanted to know. Is it possible to find that out? I've haven't been able to figure it out on my own on my phone or dad's computer. Could someone please help me out thanks.

Sincerely,

Kristi
