Do you use an iphone with T-Mobile?

Do you only use it with wifi?
Guess again
T-Mobile charged me $50 for the use of 12MB of data

They blame it on the fact that I was using an iphone, and not a T-Mobile phone. Even though I did NOT have a data plan. They said it is all because of the use of an iphone.
Funny thing is it ONLY happened when I left them on my last bill. Never in the 2 1/2 years before when I was using an Iphone.

Just a warning......
Watch out for T-Mobile if you are using an iphone.

I do not want others to get the surprise billing that I did.
And they wonder why I left them
