re: Any way to get Gmail & yahoo on same app? (Android)

Access gmail from pc it's easier, go into settings and add account, you'll input your yahoo name/pass... Easy to do. When you're in gmail afterwards you can send /recv from either just make sure you know whiich one is showing.

PS make sure to set the reply to rule as "always reply with account original email was sent to" or you'll get a yahoo email and reply with gmail without knowing
