my blackjack 2 is slow

How would cancel my ATT contract after 1 year?
Okay, so you have a Blackjack 2 for almost a year, and I I'm happy. I would really get a Samsung Epix (because I like the keyboard for the Blackjack 2, but my Blackjack is fucked (Bein slow, freeze, taking 20 minutes to activate the middle button does not work …). My parents told me that if I look the price of everything (write, phone, …), etcetc be taken into account. I already know Epix that because I tried one of my friends for a day
. So how much would it cost to cancel my Blackjakc 2 lines for ATT? I have the full text and plan my family (4 lines), so I keep hearing that would be about $ 175.00. Is this true? What about their experiences with having a line canceled? Thank you! Maddy NGDOs >–^—
Their concerns about $ 110, 5-10 dollars could be more if it were in the one-year contract complete. It is $ 175 minus $ 5 per month phone.
