I have two POP3 accounts that are POP3.live, and they survived the iOS 5 upgrade fine on iPad, iPhone and iPod touch.
Do I need to do something to them protectively? I don't know what's the difference between POP3 and IMAP. Is there some kind of process you go through to convert so that you can keep the same email address(es)? What's the incentive?
Glad to hear things went smoothly when you upgraded. That's apparently the case for a majority of folks, but unfortunately some didn't fare so well.
This isn't really the forum to discuss email protocols, however it's safe to say that IMAP is superior to POP3 on a number of levels. These are a few:
- Read all of your mail (Inbox, Saved, Drafts, Sent, etc.) on all of your devices; iPad, computer, smart phone, etc.
- Easily switch OS or email programs.
- Avoid webmail outages.
- Keep an extra copy of your messages to avoid data loss.
- Consistency since the status of all of your mail is always the same across all devices due to continual two-way communication.
Yes, you can switch from POP3 to IMAP and continue to use your current email domain address(es). Switching is slightly different for different ISP's and mail programs (Apple's Mail, MS Outlook, etc.).
Here's Apple's iPad Mail support page:

The best thing to do is to get a little education about the differences (it's really not that complicated) and then follow some common directions for switching from POP3 to IMAP. ISP's (Internet Service Providers - the company that you pay for broadband service) usually have information on their websites about setting up mail clients. If not, Google "POP3 Vs IMAP" or something similar, you'll find all sorts of information.
