I'm currently in an at&t family plan with my father who has an iPhone 4. As of now, I have a 'dumb phone' for which we pay $15/month for unlimited data, and $5/month for 200 texts, in addition to the cost of having the line for talk (I believe it's $10/month?). I've been looking into upgrading to an iPhone 4 on contract price, however I'm not sure how this would affect our monthly bill; could anyone give me some insight into how much extra we'd pay.
Thanks so much
