It looks like iTunes did an update last night at about midnight that completely broke Feed Flipper. I hate to say it, but I don't think this fix will be easy--I don't know how long it will be before I crack what they have done. Maybe months. I'm disabling error reporting for the time being so RSS inboxes don't fill with spam. A new version is in progress and expected to be finished by May 1 2011.
Do you Android blokes use anything similar to turn a crappy iTunes only feed into something useable?
EDIT: Seems to be working but ive only been able to add a feed directly from the iTunes site and not the podcast link on the hosts site.
Anyhoo, all is good it seems now that ive been able to have a mess around with it at home for a while.
If you don't use the iTunes site but want one of the feeds that's only available there give Feed Flipper a whirl.
