from vodafone themselves which is opposite of what is said above
"Hello Liam,
Thank you for contacting Vodafone.
Let me inform you that when you purchase a Blackberry and start our Pay G services and opt in for Blackberry Services you can use Blackberry Instant messaging, Blackberry Push Mail, Blackberry Apps etc. from that service. When you opt in for Text and Web freebie you also get Web allowance for normal web browsing which does not include Blackberry services as mentioned above.
I trust that the above information is helpful.
Kind regards,
"
