My3g is currently experiencing problems with all apps except for the App Store and iTunes. Hidef Youtube is not working, and other 3rd party apps are not being tricked into thinking its on WiFi. Reinstalling and rebooting does not yield a fix. Please debug now.
Cool! It worked. To fix, uninstall all rock apps with the rock interface. Then, uninstall rock through cydia. Then reinstall rock. Open rock, and install all your previously owned packages. My3g is all better!!!
Bought my3g today and havnt had it work with FaceTime the 10 times I've tried it. Just uninstalles my3g and rock and reset network settings and reinstalled both of them. Still won't work on 3G, just says call failed
