well... i dont like the omnia. its not my type of phone. i think the mythic has more features for a 13 year old girl. the omnia is like to high techy lol but.. the texting is alittle difficult on the omnia. the mythic is a new phone and it has great features (to me). look on youtube and see the phone reviews for the 2 phones. she should love it. plus she should only use it for texting and calling and maybe internet. if she wants something to entertain her and something more exciting she should get a ds i or something
