Enabling 3G on HTC Hero (2.1) after upgrade

[arcane#AC]

Hi Fellows,

I have HTC Hero GSM Orange UK ROM in Canada working with Rogers and was upgraded to 2.1 last month. Since then, I am unable to get the phone work with 3G at all :-( I am not able to find the option at all as well :-( Any responses/pointers will be appreciated.

Thanks in advance.
