Minor annoyances, when consciously observed and acted on, can lead to great positive change.
Checking various email addresses in a number of environments (iPhone, private Macbook, work Macbook, webmail), I found myself annoyed by the following: emails that I had read on one device would still be marked as unread on other devices. I had heard of the IMAP standard (as opposed to POP/SMTP), whereby the clients are kept in synch with the server instead of downloading emails. Re-configuring the email providers and email clients was quick enough.
However, I ran into a problem with the iPhone: For some reason, when entering the account details, the iPhone will auto-select the account to be a POP account. Now here is the trick: This auto-selection only works, if you enter the _correct_ account details. So, in order to self-select IMAP over POP, I misspelled the password and – tada – the iPhone presented me with the full config details of the account and I was able to select IMAP.
Just in case, anyone else runs into the same problem…
