IPod Touch can't connect to imap/smtp server

Question

I have a 1st generation iPod Touch running iOS 3.1.3 (it's the iPhone OS, and I suspect that this problem is OS related).  I have half a dozen gmail accounts to which I connect to over WiFi using IMAP for reading and SMTP for sending.  It works flawlessly at home and almost always in public WiFi (Tim Hortons, McDonalds, Second Cup, Starbucks, malls, etc.).  Today, I tried it at another site, and all I got were the messages in the subject line (to the best of my memory).  Googling revealed that 2 ways to solve this was to re-enter the login information and to reset to factory default settings.  Obviously, I don't want to do the latter until I exhausted all possibilities.  However, the former doesn't work.  In fact, even after going to locations where email worked in the past, I continued getting the above error messages.  Web access, however, is fine.
When I got home, email worked flawlessly.  That means I don't have to reset to factory default.  But what could cause such a departure from the long history of proper functionality?

Answer 1

could you please explain how this is a gmail issue?
You are having a problem connecting to your email severs, which as you stated is Gmail ("half dozen gmail accounts")  You have recreated the accounts in the device without success.  THis all speaks to Gmail issues. Google has recently changed the Gmail configuration and severs. AFAIK, there is no incompatiblity with iOS 3.1.3, but you need to verfy with Google.
As for being an iPod Touch, I *suspect* that the OS is more likely the problem than the hardware.
Huh?  What's that got to do with iPhones?  Both the iPhone and iPod Touch use iOS.  Your post is about an iPod Touch 1G and belongs in the iPod Touch forum, where it has already been moved.
