The only way I get notified that I have a new GMail is when I have sync turned on for my GMail account, with background data and auto sync active.
If I turn sync off (to save the battery), I never receive notice of new emails.
Is there someplace on Google to change my push settings?
I read somewhere that I may need to delete and re-iinstall my Gmail account on the Droid. I'm a bit wary to do that, as everything else on the phone works fine. I don't want to lose anything (contacts, emails, SMSs, etc)
