I'm thinking of it this way, if I bought my 14 year old child an iphone and she broke it, I'd be really upset...if he/she lost it then I'd be more than upset cos the usage of whoever found it is on my bill. A house phone is by far enough for a teenager in my view, except for the need to call me to come get him/her in case of an emergency and perhaps to text friends to meet up with. I honestly see no reason for having anything remotely expensive cos of the risk of loss. There is, of course, the option of you finding some work and saving for it yourself though!
