Anyone else notice, no additional incurred charges for Rogers Unlimited Social Networking plan when browsing, or using other third party applications?

I'm on Koodo's Social Networking plan, which is supposed to offer the same features as most other Social Network-based plans. I have no "data" per-se, but unlimited FB/Twitter/MSN/Gmail/practically any instant messaging service.

My Curve 8530's internet browser doesn't let me open any pages if I'm not connected to Wifi, but practically any app that uses data (Youtube, Specific website-based apps, etc) lets me use their services indefinitely. Either an oversight on the service provider's part, or...just plain laziness lol.
