Right now I have a blackberry bold with unlimited text + data. Would my monthly bill go up at all? I'm on plan with my family and my dad has an iphone, idk if that matters. Right now all 4 of us have unlimited text, and me, my dad, and my sister all have unlimited data (mom doesn't). I've looked through our account to try and figure out if my portion of the bill would increase if I got an iphone, but I cant figure it out. Any ideas?? Thanks!!
