I have an iPhone with the same AT&T unlimited data plan that came with my first iPhone (3G) from 2008. I previously asked about the grandfathered plan in another thread. Now I am curious: If you still have the AT&T grandfathered unlimited data plan, how much are you paying monthly, including all voice, data, text message, etc. costs? Below is my bill. I am paying $63 per month. Is that good? I really like the plan because ATT raised the throttling limit to 22GB in a month back on September 15. Please answer the poll.
