I deleted my Google account and re-created it. The behavior is still the same. I also report that my wife's situation is basically the same (SIM card, PR1.1, but she is only using Gmail) and she has exactly the same problem. Thanks a lot for a quick reply!
Yay, mine is working now! I did the "Restore settings" and now it's syncing again. Recreating email accounts didn't help, but restoring settings did the job. Now it's a perfect phone again.
my n950 keep on forgetting email passwords ( wants me to fill in manually) on all the accounts. is there something wrong with my setting, or is it just the email client playing up?
