I have a Blackberry curve. I´m in Argentina and my hostel has a wifi which I have connected to. The wifi logo is lit up but when i try to use facebook app or the browser it won´t load anything except the vodafone wap page. At first my twitter app was still in use and i received notifications on that but one i logged out of twitter i could no longer log back in. Twitter just says ´Twitter services currently unavailable´ and facebook just keeps refreshing feed until it comes up with error message 100. I did turn off data roaming before i left but it should still be working in wifi zones? please help?
