Is a blackberry the same thing as a blackjack?

Nope. they normaly look very similur but a blackjack aucaly uses windows, unlike a blackberry. Also when you get a blackberry (no matter who your provider is) the compnay blackberry makes you pay generaly an 30 dollar data plan fee. the price of this can vary a little. but with the blackjack you can choose to have the data package and it normaly alot cheeper. i would go with the blackjack.
