Okay, need some advice for what I'm sure is a stupid question. A few months ago (actually the same day I got my iPhone 4) I took my 3G and jailbroke it. Then I unlocked it to take it overseas for use while I traveled. Now I'm back home and thought it would be cool to use the 3G for tethering. I really want to hook it up to my netbook for some mobile stuff and then to hook it up to my xbox to perform an update. So, as of now my 3G is jailbroken and unlocked and not activated on any network. Can I get a pay-as-you-go sim card from somewhere put it on the 3G And be good to go? Where could I get such a sim card? Everywhere around me seems to only have cards to re-up you minutes.. Also I've installed tetherme from cydia, so I think all I'm missing now is a way to get connected. Any help? Thanks!
