How to ask politely for an iPhone?

So the situation is sorta awkward. I'm planning on asking my father but he hasn't really been there for the past few years, but he recently came back. Last month he bought my brother an iPhone. I'm sure he won't have a problem with it because he is very wealthy right now, I just don't know how to ask. I was thinking of doing it over texting because i haven't seen him in a couple years. I was going to say something along the lines of "Since my birthday is a couple weeks after we're seeing each other, I was hoping you would do the same for me as you did for Ricky and get me an iPhone" Is it rude? Should i do it in person?

Please Sir… May I have an Iphone?
