Are the jailbreaks worth it? Untethered or tethered?
Untethered as far as I know and works on mine. But the apps...well that's a different thing altogether. I've just restored, synced the fresh install (with my Wi-Fi settings included) and gonna re-try it now, hoping not to lose half my default apps from the home screen.

that's crazy. on my ipod it just works fine.
Works for me too on the new touch. But the 3G remember it uses older hardware so it's gonna have problems being a bit slow and all, which is ridiculous considering it doesn't get all the features we were lucky enough to get e.g. wallpapers, app switching, Safari auto-fill etc etc so it should run the same, if not better. I still think there's a serious memory leak issue on 4.0.
