I take it you're using a 3G phone. Well i used mine this way to get on the net and check emails but some stuff was restricted by my service, Vodafone. These forums gave me problems and other sites where i had to sign in.. I did get a message telling me that i can unlock the restrictions by paying vodafone a Ģ using a credit card to prove my age and then they would re emburse me Ģ2 off my next bill.

So maybe you need to talk to your network provider?
