What does "unlimited acces to facebook" mean for a phone plan?

[Anmol]

Ok so I am getting the HTC sensation XL from optus and on the 24month plan it says unlimited access to Facebook,twitter,...(some other social sites). Does this mean I can use Facebook while on 3G without using the 200mb data per month. And is 200mb enough for light using of the internet, to check cricket scores and stuff?

yes, it means that anytime you are on facebook, or twitter, and whatever else was outlined for social networking sites in your contract, you are NOT using any of your 200mb data, its free and clear.
200mb is definately not alot, but if cricket scores are all you are checking should be fine i wouldnt recommend you do anything like youtube or downloading. You wont be able to do much of anything really. but all smart phones have the capability to connect to a wifi network. so use that as much as you can whenever you are connected to a wifi internet network you will not be using any of your 200mb.
