Im on Orange and when I got mine they told me I could use it straight away.....what they failed to mention was that I needed a Blackberry add on to my tariff. Only found it out after spending a week on and off trying to set all its features up.

IIRC when you have the add on applied to your tariff you should be able to set up your email and Internet more or less straight away.

And the Facebook app is shite, I always used Facebook on the phone internet. The only thing its good for is that it allows you to upload pics to your Facebook account as soon as you have taken them from the picture menu.

HTH!
