But if you always delete shows when you're done (to save precious space), the quick link is gone -- instead, you have to type the relevant podcast name into the iTunes app's Search bar. What a pain! So here's a way to make podcast links list in Mobile Safari that toss you right to the show's page in iTunes:
- Go to iTunes on your Mac/PC, look up the podcast you want to bookmark in the store.
- Right next to the Subscribe button is a down arrow; click that and choose Copy Link.
- Paste this link into an email addressed to the account you access on your iPhone (or any other method for getting text snippets from your computer to your iPhone). Send a bunch of links in one email and save time.
- Open the email on your iPhone. A long press on the link pops up the option to copy it.
- Open Mobile Safari and bookmark whatever page is showing. (It doesn't matter what it is; we end up editing it anyway.)
- Go to the Bookmark menu, find the bookmark you just made, and tap Edit. Change the name to the name of the podcast, clear the old URL, and paste the link in the URL field.
[robg adds: I haven't tested this one, but if you're willing to sync one time, it seems you could simplify it by bookmarking the podcast URLs on the Mac/PC version of Safari first, then syncing your iPhone (assuming you sync Safari bookmarks).]
