Evening,
Do you have the BB option on your number? (£5/month)
To get full Blackberry services (this includes the facebook app and BB Browser) on PAYG you need to blackberry Internet Service added - also gives u BBM and email etc - these all go through the BB server
"Get email and BlackBerry Messenger on Pay as you go
For email and BlackBerry Messenger on your phone, you need to opt in to the BlackBerry Internet Service. It's £5 for 30 days – and we’ll take £5 from your credit each month unless you opt out.

Log in or register for My account to opt in.

Call us free on 40035 from your Vodafone Pay as you go BlackBerry."
There may be a way round it if you have another browser on your handset (certainly used to work). If it came from Vodafone check if it has a Vodafone Live! icon...
I do not have the BB option. I only want to use the Browser and don't need the BB Email and BBM functions. I have now installed Opera Mini on my BB and changed the APN settings on my phone. Now I am able to use the Opera Browser. 
At least something. But still I can't access the FB app, it's only working when I am connected by Wifi. Do you or does anybody else know how I can use the FB app through my mobile internet? But I don't really want to option in to BIS as it costs me £5 extra per month.
Thanks!!
