This is makin' me flippin' nuts: 1. I add an account or two (POP3 or IMAP) to the built-in Android Email or Android Market K-9 app, 2. The non-GMail e-mail works mostly OK for some time (a day or two, an hour or two, etc.); (I do get connection errors, I can't completely delete POP3 email, there's no POP3 auto-checking nor notifications, etc.--for now these annoyances are manageable.), 3. At some point in the future, I go into the app to check mail, and POOF! Everythin' B gone. I'm greeted with the setup screen, as though I had not created the account(s) previously, 4. I recreate the account(s), 5. GOTO 2. It's gettin' old... WTF? Any clues here?
