I was lulled by this forum into believing that I could keep my unlimited data plan. Seems like one of my new phones has unlimited data and the other now has a 3G plan which I had to have because ordering my new IPhone kicked me off data all together. So we took the 1st phone kicked off the data plan into ATT store and it was restored to our unlimited data plan. When second phone was kicked off data plan before new phone arrived I contacted someone through this forum who led me to believe she could help. She said I had to get a $30 3G data plan and to use my phone for now and then she would help restore my unlimited data plan. She has since disappeared and I'm left with two data plans and I'm sure a higher bill.
So I'd be wary of the assurances made on this forum.
Since I don't even use that much data, I'm thinking I might just return two new phones and start over with another provider. This has been incredibly annoying, time consuming and seemingly futile.
