email.

I've had the incredible Droid HTC for 3 days now. I set it up using the preset home pages. I chose HTC version. I put wallpaper up. It was great. I set up both my emails (one Comcast one yahoo) from the email widget I was able to toggle between the 2 of them by swiping at T the top. I didn't have to manually select the other from a menu. This morn I accidentally threw the widget away. I added it back but the feature of boggling back and forth between the 2is gone. What did I do? How do I undo it? I don't care if that they don't share an inbox. I liked the way it was. Please help me. I'm new. I not very tech savy so please tryto keep it simple. Thanks so much.
