My best friend is addicted to her phone?....?

My best friend is addicted to her new BlackBerry (the phone) and it's starting to get on my nerves. Don't get me wrong, I'm not jealous of her at all as I have the same phone as her and I love it as much as the next person but she is actually on it all the time. She uses it at school even though we're not allowed. I feel like if I want to communicate with her nowadays I have to text her instead of being able to speak to her in person. Today she was using it at break time at school and a girl came up to her and said, "I like your phone." and she said, "Thanks I guess but everyone's obsessed with my phone! They're just jealous because they probably want the same phone as me, after all it is amazing!". Shall I do anything about it? Thanks!
