Sprint rip off , Internet

I have an account with sprint and have had this account for about seven years. I have a shared plan-everything plan so I am already paying for data, well I added two lines to this already shared plan and now sprint is charging me and additional $10.00 per line for the data plan I already pay for. When I called Sprint to inquire about the bill I was told that all smart phones activated after 1/31/2011 will have this new charge. I was not informed of this when I purchased the phone and added them to my plan.
I also Have a blackberry 8350I that has not worked in a week so I went to my local sprint store and was told the phone needed to be updated, now keep in mind my brother has the exact same phone with no problems, well I did the update as instructed because the store associate, she said it would take about an hour and a half but I could do this update at home, I did the update at home and two and a half hours later I still have the same problem. so thank you Sprint for ripping me off and giving me the run around.
