I think I've just about had it with the control Apple has here, and the way AT&T uses their relationship to do this. Cripple SlingPlayer, cripple Skype, block Google Voice, etc. I"m getting a myTouch 3G next week when it's released, and odds are I'll be leaving AT&T.
I remember thinking when the App Store was first launched that stuff like this would end up happening, and sure enough it's happening over and over again.
I know it's not Apple, it's AT&T. I will no longer be giving my business to AT&T. I understand I'll be getting less of a phone, but I will not support this crap any longer.
