I'm not sure if I posted this in the right forum, but I have a samsung infuse 4g. I have 2 gmail accounts on my phone and just recently I started receiving duplicate notifications for the marketplace. My primary email which is the only account I've used for the marketplace shows all updates including installed/purchased/pre-installed. The secondary email which I have never used in the marketplace only shows updates for pre-installed applications. I can't seem to remove the 2nd email from the marketplace (only toggle between accounts) however I do need the email on my phone so deleting that is not an option. Does anyone else have this issue?
