For the longest time when AT&T bought Cingular, plans that were entered into under Cingular were allowed to continue under AT&T on the same terms. Given how long ago this was, I didn't have data, so I can't speak to what would have happened with a voice/data plan. However, I can see the same thing not happening with this deal. AT&T really is the antithesis of T-Mo in terms of pricing, flexibility, and customer service. I've got both (an iPhone and a Nexus One). While 3G coverage is not as readily available on T-Mo as it is on AT&T, there have certainly been many times when it has been more reliable in call quality and drops. The only upside to this? It is very likely the US will end up with unified GSM frequencies. We will see. Seriously not looking forward to this.

They likely won't take away your plan (and if they tried you'd have the ability to terminate your contract). All carriers have a policy of grandfathering in existing plans when they change theirs (as they did, for example, when they eliminated unlimited data last year). Of course that means you can't get a new phone or change a plan details without submitting to the new terms. If you're willing to live with that, it can be beneficial. Some people are on 5 year old plans and paying $10 or less for unlimited data. Carriers know this, and put up with it because they know the vast majority of their customers are going to re-up the contract regularly.
