I noticed what I believe is a software bug in Gmail App for this phone. I have 3 Gmail accounts. Each of them I set up with a slightly different signature. I receive e-mails for all 3 accounts during the day. When I reply to received emails or create new emails, Gmail App inserts a signature associated with the account which was last previously used instead of inserting a proper signature associated with the account I am currently using. The only work around I found is to discard the message with the wrong signature inserted and then repeat the process to reply or create a new email. On the second attempt Gmail App "magically" inserts the proper signature for any given account. Pretty annoying especially since on my N1 with Gingerbread that situation NEVER happened before. I am able to recreate this error every single time I switch between the accounts.
