8320 internet on Orange PAYG without paying £5 /month

I have been using a Nokia e61i for the past year with no problems at all apart from it’s now knackered.

I have now got a BlackBerry 8320 but cannot access the internet without using WiFi. I have rang Orange and they told me I had to pay £5 a month for this service.

I told them that this is a joke as I had internet on my Nokia for free, so why would I pay to have it on a different phone?

Is there any way I can get internet working on my BlackBerry without paying EXTRA?

Thanks.
