Since I upgraded my iPod Touch to OS 4 I've seen a big difference. The Wifi is a lot better, hurrah!
But the Synching of Podcasts is woeful. I download my podcasts wirelessly each morning and listen to them. This is all fine. When I plug my iPod into my computer it "synchs" it.
Now when I look at my podcasts, the timer doesn't display and I can't scrub through it anymore!!!
