Proximity Sensor Disabled by Default

[trikoy2]

Hello everyone, 1st post here. I got my T-mobile data only plan with no voice, and I'm guessing that T-mobile disabled the proximity sensor of my TP2.

My question is... did my carrier really disabled it? If yes or not, is there a way I can enable it?

I use Skype with it now, and I would like to use the proximity sensor so I won't hit buttons with my face when I'm on the phone.
