Turbo sim but no internet. please help.....

I am using iphone 3g with a turbo sim. Before the jailbreaking with quickpawn i could use internet but now no internet. only wifi. there is a sign(possibly a phone looking sign) on the right upper side of the phone. when i used internet before i needed no setup, by only keeping the data roaming on i could use internet.
what should i do? PLEASE HELP...

which sim-unlock solution are you using? some of the out of date ones do not support mobile internet...
