I got my new Hero on Friday (Reward Zone member). I came from an iPhone 3GS. I HATED at&t service.
I have set up my Yahoo account with the mail app. I set up my Gmail account as well. I can not access my Yahoo mail from the mail app when connected to Wifi. If I turn off Wifi, then I can access the mail app.
I CAN however access my Gmail account using the Gmail app on Wifi.
Has any body else experienced this or any clue on how I can get this to work with Wifi??
