Help Firewall for GT540?

[iRhyiku]

Okay So I would like a firewall for my phone as i dont have an unlimted data plan, and dont like apps accessing the internet without my say-so, but all i have tried gives me a similar error:

iptables v1.4.7
iptables v1.4.7: can't initialize
iptables table 'filter': Table does not exist (do you need insmod?)
Perhaps iptables or your kernal needs to be upgraded.

So my question:
Is it possible to get these tables? Or is there a firewall out there that will work on my phone.

Thanks in advance

EDIT:
I'm Running 2.1 ROOTED.

Disable ''Mobile Network'' (Settings>Wireless & Networks>Mobile Network & select Disable) when you don't want your phone to use data connection... & when you want to use internet, just Enable it...

That could work thanks ^^

Still want to disable it for certain apps all the time though..
