15 yars old and want a new phone; which one to choose: Blackjack 2 , or, palm centro?

i have a Blackjack II and its ALRIGHT. The palm centro has some perks. The only problem with smart phones are, u cant set all ringtones they have to be a certain size and even if u answer a text, the ringtone will keep playing till its over. Another bad thing is, when in the middle of a call, the phone will still make noise if a new message has arrived. The phones are great for Storage space and texting. But the new Razr II is a much better phone
