Having problem after adding gmail mailbox on 808 and fast going mad..
First I should say that I'm doing this on home wi-fi, no SIM card yet.
After setting Exchange ActiveSync up with my email acct, adding my gmail password, selecting what to sync and when, anything I try to do just keeps asking for my gmail password, again and again. Grrr!
By the way, I saw no certifiate warning as shown on recent page about Exchange ActiveSync by Steve L.
Any ideas what I can do other than deleting the mailbox and trying again, as that just does the same thing.
Is there some deeper cleanup that can be done before retrying, some cache to clear?
Edit: All solved!
Decided to use the microSIM from my GS2 and everything Nokia sprang to life

Exchange ActiveSync worked first time.
Only snag is that Contacts on my phone, which I worked so hard to Export from my GNex via Dropbox to Nokia Suite, now contains a LOT of duplicates.
Hopefully NS will clear up the duplicates when I next connect to the PC.
Btw, if ever you want to backup your Android Contacts, I think you will be happy with Contacts Backup Pro.
