I have an ipod 2g running 3.1.1 freshly reformatted( this problem persisted before). When I connect to my secure network, I can use EVERYTHING ( using wifi). Now I can still use everything, except for THE APP STORE!!!!! When I connect, and purchase lets say, it says that it can not connect! Any suggestions!?!?!? Thanks in advance,
Guy

There could be something up with your router settings, I've read about problems like this somewhere but I forgot where :(
