I use the Yahoo Mail app everyday. It works for me. Most of the complaints seem to be about not being able to delete multiple emails at once. Tapping the Edit button gives you check boxes to do just that. The complainers need to RTFM.

 

You could try K9. I get HTML emails in my yahoo account and in K9 all I have to do is press the "Show Images" button for the full email to show. I don't use the native email for Yahoo app so I can't help there.

 

Mine has the exact same problem after the 2.3.5 update that just rolled out. I can be viewing the message and whamo...the message content disappears.

 

2.3.5 update? Did I miss something? I don't recall the Incredible 2 ever getting 2.3.5 except by rooting.

 

Mine does the same. I'm rooted and using 2.3.3 . Html shows for hotmail and gmail but not yahoo. I got the market app and its not the best but at least i can see my damn emails

 

the provided mail does not work fully with yahoo. I went to yahoo on the browser and down loaded their app and it works fine. downside is it adds another mail icon to your desktop.

 

I think I figured this out. You know how widgets have to be in internal memory or they disappear.
I was going through the stock email settings for yahoo and found under general settings/attachment cache was set to external. I changed it to internal and no more email disappearing before my eyes.

 

nope still happening, sorry

I use the yahoo app as well and I have 4 yahoo accounts setup.
you have an accounts button top left, then you go to a different screen and over on the right there is a "manage" putton. By pressing it you can add and remove accounts.
so thats the official yahoo mail app ver 1.3.8
