Yahoo Email

I have a quick question with no time to search. Since getting my Storm, I had to change my device in the BIS, however it wouldn't work for some reason--problem with the ESN or somesuch. I setup the email via the phone just to get it to work, but now there are problems:

Signature line is deleted from the BIS file, but it still shows in emails
Emails are NOT being received online in YAHOO, but sent only to my device.

Suggestions?

Thanks

Forgot to say, I don't have time to delete and restart now. Maybe tonight, but I wanted a quick fix if it's out there. TIA
