And you are able to access blackberry services on wifi, but only sometimes on the mobile network.
What specifically does and does not work?
Have you tried setting the mobile network mode to 2G only?

Yeah, I have a data plan. I'm on Vodafone and have had my blackberry since Christmas day 2009.
With it connected to my WiFi at home, I can access everything. I can talk to people on Blackberry Messenger, I can use the Facebook app, I can go on the Internet Browser and I can send text messages, etc.
But as soon as I turn off the WiFi, or go somewhere where it can't reach/pick up my WiFi signal. None of the above works. I can OCCASIONALLY send a text or a Blackberry Message, but then the next text/sentence I type comes up with the red cross/red clock.
The signal bar usually looks normal, with the 3G showing and a full signal. Sometimes it goes to the red SOS and doesn't change back unless I reset the connection.
Basically I can only use my phone when it's connected to the WiFi.
