I've had my Pre since launch, have had no problems other than 2 soft-reboots when trying to open too many cards at once. This morning I've been getting 'Login credentials rejected' on my main gmail account. My other gmail accouont syncs fine.
I did a cold reboot of the phone, still rejected. I tried deleting the gmail account and re-adding it, now I'm getting a 'web login required' when trying to manually setup the account as imap. Anyone else having issues? I have made no changes on this particular gmail account for several weeks, I did login via web to check and all the settings seem normal.
