Forgive me if this is covered somewhere else, I tried looking without any success. I used to have a 3GS until January of this year when I lost it. At that time I was on the $30 unlimited plan. After losing it, I had to switch over to a blackberry I got from a friend, and therefore, I am now on a bb plan. I have preordered the new 4S and ready to receive it Friday. What I would like to know is if it will be possible to go back to my previous unlimited plan? Thanks in advance.
