I just recently updated my 3g iPhone to the 3.0 firmware. I was testing out a couple of apps that use wifi, remote and wifi track(I think it is called wifi track). The remote app ,I downloaded the latest 3.0 compatible version, from the AppStore. When I went to use remote, I created an ad hoc network on my laptop, it worked for a little while but then the app stopped controlling iTunes and said I needed to be on wifi. The wifi track app when I opened it gave me an error message saying: unable to initialize wifi scanner. I am just wondering if there is something wrong with either the apps or the wifi on my phone. Also wondering if anyone else had a similar problem, or if anyone could help me fix my problem?
