i got the exact same problem.. can somebody please help

ok i just jailbroke my 2g iphone running OS 3.0 with redsnow.. some of the problems have been fixed by tips from comments on here so thx guys for that.. but my last problem is im getting a error message for anything that uses internet.. error message is COULD NOT ACTIVATE CELLULAR DATA NETWORK: YOU ARE NOT SUBSCRIBED TO A CELLULAR DATA SERVICE... i never had this issue before when i was running OS 2.2.1 and jailbroken with either qwkpwn or pwngtool cant remember which one i used last.

Is anyone getting this message as well??? does redsnow completely unlock the OS??
