O2 BlackBerry bolt on?

[emcetera]

Sorry if this has been asked before – as I'm sure it has...

I just wondered if someone could clarify what's included in the O2 BlackBerry Unlimited bolt on (£10 per month)?

I'm extremely new to BB (having only got the Curve 8520 on Saturday) and am a bit wary of unwittingly running up a huge bill. I've downloaded the Facebook and Twitter apps, and often follow links to news websites etc from Twitter. I don't really use wi-fi much, as I've been using my new toy mainly on the train to work etc.

I've also heard that WAP isn't included in the bolt on – am I likely to stumble upon many charges for it?

Thanks/sorry in advance!

what is included in any browsing on your device as long as it goes through your BIS connection (which is pretty much any browser on the market (BB Browser, Bolt, Opera Mini etc) your bbm and your email push connection is what is include. Carriers call this BIS (BlackBerry Internet Service) and it is what it is include for the price.
