IPhone contract internet allowance queries?

So i'm really considering getting the iPhone 5 on contract with EE.
Was just wondering if 3gb of internet is a lot?
And does doing things like checking football scores or using twitter/facebook straight from the apps affect this?

If your asking if using the internet uses the internet, then yes. Sports score & twitter would use little amounts off data, but apps with pictures like facebook would use more, and video apps would use lots of data.

It is really difficult to say is some amount of data is a lot, like sports score would use small amounts if the scores are text only, highlight videos would use more. 3gb is probably fine if you don't watch TV, movies, or spend hours on FB.
