AT&T has had a tumultuous relationship with its own customers over the last few years, with issues stemming from its lack of network capacity being exacerbated by the hugely popular iPhone being an exclusive handset to the carrier.
Data has tended to be one of the biggest sticking points for many, the lack of ability to make a phone call not withstanding. The recent change of AT&T's data plans has only managed to muddy the waters somewhat, and now things are getting even more confusing with the news that the carrier is throttling users who are on the old unlimited data plan and use 2GB of data per month.
The obvious question now is simple: why is AT&T throttling users who use 2GB of data but continues to accept new users on the updated 3GB limit plan? No, we don't know either...
