Wow this kinda sucks. My family was about to get T-Mobile so we could pay less and eventually get ATT's services.
I had to replace my prepaid phone, and I switched providers for two reasons.
1. I don't use minutes much, and mostly want texting and data. Virgin Mobile was half the price for both unlimited
2. I was concerned about the merger, because I know I would be charged more. I don't see any way I could save money, or even keep the same price.
I really doubt you would have saved money in the long term based on my experiences with T-Mobile. I don't think they do grandfathering.
EDIT: AT&T also can terminate grandfathered plans, too. They have threatened some people on their now grandfathered unlimited data plan if they try to tether. If they actually use more than 4 GB of data, they will get throttled. Still "unlimited" but not the same. I wouldn't trust AT&T, period.
