When I purchased my phone, the Verizon store associate set my yahoo email as my primary email. In other words, whenever I accessed my contacts to send them an email, it was sent from my Yahoo account.
I also have a Gmail account because I need that account to sync my calendar and contacts with my computer.
Yesterday my phone started sending all of my email from my Gmail account.
How do I change it back so that my Yahoo account is my primary account?
I spent 30 minutes on the phone with Verizon tech support yesterday, and they were unable to help me.
