Unfortunately, the time to get out of the contract without paying the ETF was between last July when they first announced the change of terms and October when the changes went into effect.
As for being able to change the terms yourself, you could try, but there's no chance of AT&T accepting them. Conversely, your continuing to pay each month after their changes were announced was viewed as an acceptance of their terms.
The ghost data charges showing up are a whole other matter completely, and one that is effecting far more people than just the top 5%, so hopefully we'll get some kind of answer on those soon.
Did the changes go into effect in October? On my Oct and Nov 2011 bills, my data usage was 2132MB and 2807MB, respectively. I did not receive any warning back then of being in the top 5%. Am I to assume, then that 2807MB is OK?
Also we, as consumers, should be given the statistical data for each month in our bill so we know what the cap is for being in the top 5% and can therefore monitor our usage if need be. Obviously, with UNLIMITED data usage, this sounds a bit ridiculous, but at least then it isn't a surprise as to when I'm going to get that text and email!
Of course, this does not excuse the fact that I should be receiving Unlimited 3G data. I think as reasonable people, we know to expect "unlimited" to not mean truly unlimited, but when 3GB and 5GB plans are offered, "unlimited" should start somewhere past that! Heck, even Verizon had the 8GB when paying for 4GB deal a while back.
Next time they have another doubling data deal, I'm switching.
I was really looking forward to a 4G iPhone, but when 4G only puts me in the penalty box much fast than 3G, what's the point? Why have 4G at all if I can't watch movies or download large amounts of data faster than 3G? Isn't that the point, without being penalized?
I hope this isn't over yet. I hope someone gets the ball rolling. Someone needs to give this national attention and cause AT&T to reconsider this foolish tactic.
