Swap Or Buy Iphone 4, Spaw for blackberry torch 8910 white and abit of cash or buy for £250 +

Iphone 4, white, it comes with USB lead and a case. the phone has some minor cracks on the casing. in the bottom corner it has two small ones, then in the other corner it has another one, then on from the bottom corner to the middle button. and also on little one on the back. THESE DO NOT EFFECT THE SCREEN. it is in working condition. the cracks can be fixed at your local phone shop. i will either take 250 or swap for a blackberry torch 8910 white, but it has to be in perfect condition, and 50 .
