It's now been 48 hours since I subscribed to T-zones $4.99.
But still get "your plan does not support this feature" when attempting to Go to URL for wap sites I know that work.
On the phone I'm able to go to T-zones Home page and I see the T-zone animation. But, also, when I select Games & Applications I get the same "your plan does not support this feature" message.
T-mobile saying wait the full 72 hours ... though I got a feeling, it never really takes this long.
