I use Yahoo Mail many times on a daily basis, on an N800 and an N810. I have had no problems.

If you take one person who can't log on to ANYTHING and someone else who just can't log on to Yahoo Mail and say "Look, we have the same problem!!" well, that kind of thinking can prove anything.

All of you who are having this problem, try flashing, which should get you Diablo, and then tell us whether you have the problem.

Oh, and "how do you use classic view on an n800"??

Try following Yahoo's instructions. It really shouldn't take you a million years or anything.
