2 WEEKS? I'm using Firefox (I can't STAND IE). Here's the link I am using via PC https://my.t-mobile.com/Login/?rc=&dest=https%3a%2f%2fmy.t-mobile.com%3a443%2fDefault.aspx
Update: This is becoming frustrating. I was able to see the balance due that I have to pay, and make the requested changes to the account, but still got the message about the Plans and Services feature being unavailable.
