Blackberry 9700

Yesterday , I got a new cellphone :)
A blackberry 9700 . So now , my old phone (Blackberry 8900) would go to my mum`s since she needs a new phone .

I don`t exactly know if I like it or I like my old phone ? But I think I like my old one better , because it`s just .. I don`t know .
It isn`t really working , so I guess I have to call the service thing .
