Will it cost to get emails on my blackberry?

[Russell]

I have a blackberry curve 9300 on an orange 24 month contract. I get free texts minutes and some Internet. I would like to know whether it will cost me to receive and send my emails to and from my blackberry and does it cost to use Facebook and twitter at get notifications or does it just use my Internet allowance? Is there a way to get it to just access these when connected to wifi?

I would question that with your network and data bundle, useually 500mb is adequate a month for genral emails and facebook/twitter usage. its when you start watching youtube videos or tethering devices it uses more of your data.
